+Subject: [PATCH] netfilter: conntrack: cache route for forwarded connections
+
+... to avoid per-packet FIB lookup if possible.
+
+The cached dst is re-used provided the input interface
+is the same as that of the previous packet in the same direction.
+
+If not, the cached dst is invalidated.
+
+For ipv6 we also need to store sernum, else dst_check doesn't work,
+pointed out by Eric Dumazet.
+
+This should speed up forwarding when conntrack is already in use
+anyway, especially when using reverse path filtering -- active RPF
+enforces two FIB lookups for each packet.
+
+Before the routing cache removal this didn't matter since RPF was performed
+only when route cache didn't yield a result; but without route cache it
+comes at higher price.
+
+Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
+avoid holding on to dsts of 'frozen' conntracks.

+Subject: [PATCH] bridge: multicast to unicast
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Implements an optional, per bridge port flag and feature to deliver
+multicast packets to any host on the according port via unicast
+individually. This is done by copying the packet per host and
+changing the multicast destination MAC to a unicast one accordingly.
+
+multicast-to-unicast works on top of the multicast snooping feature of
+the bridge. Which means unicast copies are only delivered to hosts which
+are interested in it and signalized this via IGMP/MLD reports
+previously.
+
+This feature is intended for interface types which have a more reliable
+and/or efficient way to deliver unicast packets than broadcast ones
+(e.g. wifi).
+
+However, it should only be enabled on interfaces where no IGMPv2/MLDv1
+report suppression takes place. This feature is disabled by default.
+
+The initial patch and idea is from Felix Fietkau.

+Subject: [PATCH] net: add devm version of alloc_etherdev_mqs function
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This patch adds devm_alloc_etherdev_mqs function and devm_alloc_etherdev
+macro. These can be used for simpler netdev allocation without having to
+care about calling free_netdev.
+
+Thanks to this change drivers, their error paths and removal paths may
+get simpler by a bit.

+Subject: [PATCH] ubifs: Use dirty_writeback_interval value for wbuf timer
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Right now wbuf timer has hardcoded timeouts and there is no place for
+manual adjustments. Some projects / cases many need that though. Few
+file systems allow doing that by respecting dirty_writeback_interval
+that can be set using sysctl (dirty_writeback_centisecs).
+
+Lowering dirty_writeback_interval could be some way of dealing with user
+space apps lacking proper fsyncs. This is definitely *not* a perfect
+solution but we don't have ideal (user space) world. There were already
+advanced discussions on this matter, mostly when ext4 was introduced and
+it wasn't behaving as ext3. Anyway, the final decision was to add some
+hacks to the ext4, as trying to fix whole user space or adding new API
+was pointless.
+
+We can't (and shouldn't?) just follow ext4. We can't e.g. sync on close
+as this would cause too many commits and flash wearing. On the other
+hand we still should allow some trade-off between -o sync and default
+wbuf timeout. Respecting dirty_writeback_interval should allow some sane
+cutomizations if used warily.

+ window
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For reading flash content we use MMIO but it's possible to read only
+first 16 MiB this way. It's simply an arch design/limitation.
+To support flash sizes bigger than 16 MiB implement indirect access
+using ChipCommon registers.
+This has been tested using MX25L25635F.

+Subject: [PATCH] mtd: bcm47xxpart: move TRX parsing code to separated function
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This change simplifies main parsing loop logic a bit. In future it may
+be useful for moving TRX support to separated module / parser (if we
+implement support for them at some point).
+Finally parsing TRX at the end puts us in a better position as we have
+better flash layout knowledge. It may be useful e.g. if it appears there
+is more than 1 TRX partition.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+With the S25FL127S nor flash part, each writing to the configuration
+register takes hundreds of ms. During that time, no more accesses to
+the flash should be done (even reads).
+
+This commit adds a wait loop after the register writing until the flash
+finishes its work.
+
+This issue could make rootfs mounting fail when the latter was done too
+much closely to this quad enable bit setting step. And in this case, a
+driver as UBIFS may try to recover the filesystem and may broke it
+completely.

+
+Xilinx Spartan-3AN FPGAs contain an In-System Flash where they keep
+their configuration data and (optionally) some user data.
+
+The protocol of this flash follows most of the spi-nor standard. With
+the following differences:
+
+- Page size might not be a power of two.
+- The address calculation (default addressing mode).
+- The spi nor commands used.
+
+Protocol is described on Xilinx User Guide UG333

+
+This patch removes the WARN_ONCE() test in spi_nor_write().
+This macro triggers the display of a warning message almost every time we
+use a UBI file-system because a write operation is performed at offset 64,
+which is in the middle of the SPI NOR memory page. This is a valid
+operation for ubifs.
+
+Hence this warning is pretty annoying and useless so we just remove it.

+ op codes
+
+This patch renames the SPINOR_OP_* macros of the 4-byte address
+instruction set so the new names all share a common pattern: the 4-byte
+address name is built from the 3-byte address name appending the "_4B"
+suffix.
+
+The patch also introduces new op codes to support other SPI protocols such
+as SPI 1-4-4 and SPI 1-2-2.
+
+This is a transitional patch and will help a later patch of spi-nor.c
+to automate the translation from the 3-byte address op codes into their
+4-byte address version.

+Subject: [PATCH] mtd: spi-nor: add a stateless method to support memory size
+ above 128Mib
+
+This patch provides an alternative mean to support memory above 16MiB
+(128Mib) by replacing 3byte address op codes by their associated 4byte
+address versions.
+
+Using the dedicated 4byte address op codes doesn't change the internal
+state of the SPI NOR memory as opposed to using other means such as
+updating a Base Address Register (BAR) and sending command to enter/leave
+the 4byte mode.
+
+Hence when a CPU reset occurs, early bootloaders don't need to be aware
+of BAR value or 4byte mode being enabled: they can still access the first
+16MiB of the SPI NOR memory using the regular 3byte address op codes.

+
+erasesize is meaningful for flash devices but for SRAM there is no
+concept of an erase block so erasesize is set to 0. When partitioning
+these devices instead of ensuring partitions fall on erasesize
+boundaries we ensure they fall on writesize boundaries.

+There are two similar functions handling deletion. One handles single

+
+Function del_mtd_partitions has been moved a bit to keep all deleting

+ appropriate
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This prepares mtd subsystem for the new feature: subpartitions. In some
+cases flash device partition can be a container with extra subpartitions
+(volumes).
+
+So far there was a flat structure implemented. One master (flash device)
+could be partitioned into few partitions. Every partition got its master
+and it was enough to get things running.
+
+To support subpartitions we need to store pointer to the parent for each
+partition. This is required to implement more natural tree structure and
+handle all recursion and offsets calculation.
+
+To make code consistent this patch renamed "master" to the "parent" in
+places where we can be dealing with subpartitions.

+Some flash device partitions can be containers with extra subpartitions
+(volumes). All callbacks are already capable of this additional level of

+
+This patch makes sure we always display subpartitions using a tree

+Subject: [PATCH] mtd: partitions: add support for partition parsers
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Some devices have partitions that are kind of containers with extra
+subpartitions / volumes instead of e.g. a simple filesystem data. To
+support such cases we need to first create normal flash device
+partitions and then take care of these special ones.
+
+It's very common case for home routers. Depending on the vendor there
+are formats like TRX, Seama, TP-Link, WRGG & more. All of them are used
+to embed few partitions into a single one / single firmware file.
+
+Ideally all vendors would use some well documented / standardized format
+like UBI (and some probably start doing so), but there are still
+countless devices on the market using these poor vendor specific
+formats.
+
+This patch extends MTD subsystem by allowing to specify list of parsers
+that should be tried for a given partition. Supporting such poor formats
+is highly unlikely to be the top priority so these changes try to
+minimize maintenance cost to the minimum. It reuses existing code for
+these new parsers and just adds a one property and one new function.
+
+This implementation requires setting partition parsers in a flash
+parser. A proper change of bcm47xxpart will follow and in the future we
+will hopefully also find a solution for doing it with ofpart
+("fixed-partitions").

+Subject: [PATCH] mtd: extract TRX parser out of bcm47xxpart into a separated
+ module
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This makes TRX parsing code reusable with other platforms and parsers.
+
+Please note this patch doesn't really change anything in the existing
+code, just moves it. There is still some place for improvement (e.g.
+working on non-hacky method of checking rootfs format) but it's not
+really a subject of this change.

+ it
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+So far were were allocating struct bgmac in 3 places: platform code,
+bcma code and shared bgmac_enet_probe function. The reason for this was
+bgmac_enet_probe:
+1) Requiring early-filled struct bgmac
+2) Calling alloc_etherdev on its own in order to use netdev_priv later
+
+This solution got few drawbacks:
+1) Was duplicating allocating code
+2) Required copying early-filled struct
+3) Resulted in platform/bcma code having access only to unused struct
+
+Solve this situation by simply extracting some probe code into the new
+bgmac_alloc function.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Adding struct bcma_mdio was a workaround for bcma code not having access
+to the struct bgmac used in the core code. Now we don't duplicate this
+struct we can just use it internally in bcma code.
+
+This simplifies code & allows access to all bgmac driver details from
+all places in bcma code.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds support for using bgmac with PHYs supported by standalone PHY
+drivers. Having any PHY initialization in bgmac is hacky and shouldn't
+be extended but rather removed if anyone has hardware to test it.

+Subject: [PATCH] net: phy: broadcom: Add BCM54810 PHY entry
+
+The BCM54810 PHY requires some semi-unique configuration, which results
+in some additional configuration in addition to the standard config.
+Also, some users of the BCM54810 require the PHY lanes to be swapped.
+Since there is no way to detect this, add a device tree query to see if
+it is applicable.

+
+Implement the HW design team recommended workaround in for 7278. Since
+the GPHY now returns its revision information in MII_PHYS_ID[23] we need
+to check whether the revision provided in flags is 0 or not.

+Starting with commit 5b4e29005123 ("net: phy: broadcom: add
+bcm54xx_auxctl_read") we have a reading helper so use it and avoid code
+duplication.
+It also means we don't need MII_BCM54XX_AUXCTL_SHDWSEL_MISC define as
+it's the same as MII_BCM54XX_AUXCTL_SHDWSEL_MISC just for reading needs
+(same value shifted by 12 bits).

+Subject: [PATCH] net: phy: broadcom: rehook BCM54612E specific init
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This extra BCM54612E code in PHY driver isn't really aneg specific. Even
+without it aneg works OK but the problem is no packets pass through PHY.
+
+Moreover putting this code inside config_aneg callback didn't allow
+resuming PHY correctly. When driver called phy_stop and phy_start it was
+putting PHY machine into RESUMING state. After that machine was
+switching into AN and NOLINK without ever calling phy_start_aneg. This
+prevented this extra setup from being called and PHY didn't work.
+
+This change has been verified to fix network on BCM47186B0 SoC device
+with BCM54612E.

+Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support
+for LZO compression in regcache, but there were never any users added
+afterwards. Since LZO support itself has its own size, it currently is
+rather a deoptimization.
+
+So make it optional by introducing a symbol that can be selected by
+drivers wanting to make use of it.
+
+Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).

+I tried using google to find any users (even out-of-tree ones), but at
+best I found a single driver submission that was switched to RBTREE in
+subsequent resubmissions (MFD_SMSC).
+
+One could maybe also just drop the code because of no users for 5 years,
+but that would be up to the maintainer(s) to decide.

+Subject: hack: arch: powerpc: drop register save/restore library from modules
+
+Upstream GCC uses a libgcc function for saving/restoring registers. This
+makes the code bigger, and upstream kernels need to carry that function
+for every single kernel module. Our GCC is patched to avoid those
+references, so we can drop the extra bloat for modules.

+Subject: misc: owl-loader for delayed Atheros ath9k fixup
+
+Some devices (like the Cisco Meraki Z1 Cloud Managed Teleworker Gateway)
+need to be able to initialize the PCIe wifi device. Normally, this is done
+during the early stages of booting linux, because the necessary init code
+is read from the memory mapped SPI and passed to pci_enable_ath9k_fixup.
+However,this isn't possible for devices which have the init code for the
+Atheros chip stored on NAND in an UBI volume. Hence, this module can be
+used to initialze the chip when the user-space is ready to extract the
+init code.

-Subject: netfilter: conntrack: cache route for forwarded connections
-
-... to avoid per-packet FIB lookup if possible.
-
-The cached dst is re-used provided the input interface
-is the same as that of the previous packet in the same direction.
-
-If not, the cached dst is invalidated.
-
-For ipv6 we also need to store sernum, else dst_check doesn't work,
-pointed out by Eric Dumazet.
-
-This should speed up forwarding when conntrack is already in use
-anyway, especially when using reverse path filtering -- active RPF
-enforces two FIB lookups for each packet.
-
-Before the routing cache removal this didn't matter since RPF was performed
-only when route cache didn't yield a result; but without route cache it
-comes at higher price.
-
-Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
-avoid holding on to dsts of 'frozen' conntracks.

- interface is down
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Network managers like netifd (used in OpenWRT for instance) try to
-configure interface options after creation but before setting the
-interface up.
-
-Unfortunately the sysfs / bridge currently only allows to configure the
-hash_max and multicast_router options when the bridge interface is up.
-But since br_multicast_init() doesn't start any timers and only sets
-default values and initializes timers it should be save to reconfigure
-the default values after that, before things actually get active after
-the bridge is set up.

-Subject: [PATCH] bgmac: leave interrupts disabled as long as there is work
- to do
-
-Always poll rx and tx during NAPI poll instead of relying on the status
-of the first interrupt. This prevents bgmac_poll from leaving unfinished
-work around until the next IRQ.
-In my tests this makes bridging/routing throughput under heavy load more
-stable and ensures that no new IRQs arrive as long as bgmac_poll uses up
-the entire budget.

-Subject: [PATCH] bgmac: fix DMA rx corruption
-
-The driver needs to inform the hardware about the first invalid (not yet
-filled) rx slot, by writing its DMA descriptor pointer offset to the
-BGMAC_DMA_RX_INDEX register.
-
-This register was set to a value exceeding the rx ring size, effectively
-allowing the hardware constant access to the full ring, regardless of
-which slots are initialized.
-
-To fix this issue, always mark the last filled rx slot as invalid.

-Subject: [PATCH] fib_trie: Fix /proc/net/fib_trie when
- CONFIG_IP_MULTIPLE_TABLES is not defined
-
-In recent testing I had disabled CONFIG_IP_MULTIPLE_TABLES and as a result
-when I ran "cat /proc/net/fib_trie" the main trie was displayed multiple
-times. I found that the problem line of code was in the function
-fib_trie_seq_next. Specifically the line below caused the indexes to go in
-the opposite direction of our traversal:
-
- h = tb->tb_id & (FIB_TABLE_HASHSZ - 1);
-
-This issue was that the RT tables are defined such that RT_TABLE_LOCAL is ID
-255, while it is located at TABLE_LOCAL_INDEX of 0, and RT_TABLE_MAIN is 254
-with a TABLE_MAIN_INDEX of 1. This means that the above line will return 1
-for the local table and 0 for main. The result is that fib_trie_seq_next
-will return NULL at the end of the local table, fib_trie_seq_start will
-return the start of the main table, and then fib_trie_seq_next will loop on
-main forever as h will always return 0.
-
-The fix for this is to reverse the ordering of the two tables. It has the
-advantage of making it so that the tables now print in the same order
-regardless of if multiple tables are enabled or not. In order to make the
-definition consistent with the multiple tables case I simply masked the to
-RT_TABLE_XXX values by (FIB_TABLE_HASHSZ - 1). This way the two table
-layouts should always stay consistent.

-Subject: [PATCH] fib_trie: Fix trie balancing issue if new node pushes down
- existing node
-
-This patch addresses an issue with the level compression of the fib_trie.
-Specifically in the case of adding a new leaf that triggers a new node to
-be added that takes the place of the old node. The result is a trie where
-the 1 child tnode is on one side and one leaf is on the other which gives
-you a very deep trie. Below is the script I used to generate a trie on
-dummy0 with a 10.X.X.X family of addresses.
-
- ip link add type dummy
- ipval=184549374
- bit=2
- for i in `seq 1 23`
- do
- ifconfig dummy0:$bit $ipval/8
- ipval=`expr $ipval - $bit`
- bit=`expr $bit \* 2`
- done
- cat /proc/net/fib_triestat
-
-Running the script before the patch:
-
- Local:
- Aver depth: 10.82
- Max depth: 23
- Leaves: 29
- Prefixes: 30
- Internal nodes: 27
- 1: 26 2: 1
- Pointers: 56
- Null ptrs: 1
- Total size: 5 kB
-
-After applying the patch and repeating:
-
- Local:
- Aver depth: 4.72
- Max depth: 9
- Leaves: 29
- Prefixes: 30
- Internal nodes: 12
- 1: 3 2: 2 3: 7
- Pointers: 70
- Null ptrs: 30
- Total size: 4 kB
-
-What this fix does is start the rebalance at the newly created tnode
-instead of at the parent tnode. This way if there is a gap between the
-parent and the new node it doesn't prevent the new tnode from being
-coalesced with any pre-existing nodes that may have been pushed into one
-of the new nodes child branches.

-
-The trie usage stats were currently being shared by all threads that were

-performing lookups simultaneously the trie would begin to cache bounce
-between those threads.
-
-In order to prevent this I have updated the usage stats to use a set of

-Subject: [PATCH] fib_trie: Make leaf and tnode more uniform
-
-This change makes some fundamental changes to the way leaves and tnodes are
-constructed. The big differences are:
-1. Leaves now populate pos and bits indicating their full key size.
-2. Trie nodes now mask out their lower bits to be consistent with the leaf
-3. Both structures have been reordered so that rt_trie_node now consisists
- of a much larger region including the pos, bits, and rcu portions of
- the tnode structure.
-
-On 32b systems this will result in the leaf being 4B larger as the pos and
-bits values were added to a hole created by the key as it was only 4B in
-length.

-Subject: [PATCH] fib_trie: Merge tnode_free and leaf_free into node_free
-
-Both the leaf and the tnode had an rcu_head in them, but they had them in
-slightly different places. Since we now have them in the same spot and
-know that any node with bits == 0 is a leaf and the rest are either vmalloc
-or kmalloc tnodes depending on the value of bits it makes it easy to combine
-the functions and reduce overhead.
-
-In addition I have taken advantage of the rcu_head pointer to go ahead and
-put together a simple linked list instead of using the tnode pointer as
-this way we can merge either type of structure for freeing.

-Subject: [PATCH] fib_trie: Merge leaf into tnode
-
-This change makes it so that leaf and tnode are the same struct. As a
-result there is no need for rt_trie_node anymore since everyting can be
-merged into tnode.
-
-On 32b systems this results in the leaf being 4 bytes larger, however I
-don't know if that is really an issue as this and an eariler patch that
-added bits & pos have increased the size from 20 to 28. If I am not
-mistaken slub/slab allocate on power of 2 sizes so 20 was likely being
-rounded up to 32 anyway.

-Subject: [PATCH] fib_trie: Optimize fib_table_lookup to avoid wasting
- time on loops/variables
-
-This patch is meant to reduce the complexity of fib_table_lookup by reducing
-the number of variables to the bare minimum while still keeping the same if
-not improved functionality versus the original.
-
-Most of this change was started off by the desire to rid the function of
-chopped_off and current_prefix_length as they actually added very little to
-the function since they only applied when computing the cindex. I was able
-to replace them mostly with just a check for the prefix match. As long as
-the prefix between the key and the node being tested was the same we know
-we can search the tnode fully versus just testing cindex 0.
-
-The second portion of the change ended up being a massive reordering.
-Originally the calls to check_leaf were up near the start of the loop, and
-the backtracing and descending into lower levels of tnodes was later. This
-didn't make much sense as the structure of the tree means the leaves are
-always the last thing to be tested. As such I reordered things so that we
-instead have a loop that will delve into the tree and only exit when we
-have either found a leaf or we have exhausted the tree. The advantage of
-rearranging things like this is that we can fully inline check_leaf since
-there is now only one reference to it in the function.

-Subject: [PATCH] fib_trie: Update meaning of pos to represent unchecked
- bits
-
-This change moves the pos value to the other side of the "bits" field. By
-doing this it actually simplifies a significant amount of code in the trie.
-
-For example when halving a tree we know that the bit lost exists at
-oldnode->pos, and if we inflate the tree the new bit being add is at
-tn->pos. Previously to find those bits you would have to subtract pos and
-bits from the keylength or start with a value of (1 << 31) and then shift
-that.
-
-There are a number of spots throughout the code that benefit from this. In
-the case of the hot-path searches the main advantage is that we can drop 2
-or more operations from the search path as we no longer need to compute the
-value for the index to be shifted by and can instead just use the raw pos
-value.
-
-In addition the tkey_extract_bits is now defunct and can be replaced by
-get_index since the two operations were doing the same thing, but now
-get_index does it much more quickly as it is only an xor and shift versus a
-pair of shifts and a subtraction.

-starts coming close to the 2^32 root node size which would require
-something like 1.5 billion addresses.
-
-I chose unsigned long instead of unsigned long long since I do not believe
-it is possible to allocate a 32 bit tnode on a 32 bit system as the memory
-consumed would be 16GB + 28B which exceeds the addressible space for any
-one process.

-Subject: [PATCH] fib_trie: Push rcu_read_lock/unlock to callers
-
-This change is to start cleaning up some of the rcu_read_lock/unlock
-handling. I realized while reviewing the code there are several spots that
-I don't believe are being handled correctly or are masking warnings by
-locally calling rcu_read_lock/unlock instead of calling them at the correct
-level.
-
-A common example is a call to fib_get_table followed by fib_table_lookup.
-The rcu_read_lock/unlock ought to wrap both but there are several spots where
-they were not wrapped.

-- * in the current node. tn->full_children is the number of "full"
-- * children, that is non-null tnodes with a skip value of 0.

-Subject: [PATCH] fib_trie: Add functions should_inflate and should_halve
-
-This change pulls the logic for if we should inflate/halve the nodes out
-into separate functions. It also addresses what I believe is a bug where 1
-full node is all that is needed to keep a node from ever being halved.
-
-Simple script to reproduce the issue:
- modprobe dummy; ifconfig dummy0 up
- for i in `seq 0 255`; do ifconfig dummy0:$i 10.0.${i}.1/24 up; done
- ifconfig dummy0:256 10.0.255.33/16 up
- for i in `seq 0 254`; do ifconfig dummy0:$i down; done
-

-Subject: [PATCH] fib_trie: Push tnode flushing down to inflate/halve
-
-This change pushes the tnode freeing down into the inflate and halve
-functions. It makes more sense here as we have a better grasp of what is
-going on and when a given cluster of nodes is ready to be freed.
-
-I believe this may address a bug in the freeing logic as well. For some
-reason if the freelist got to a certain size we would call
-synchronize_rcu(). I'm assuming that what they meant to do is call
-synchronize_rcu() after they had handed off that much memory via
-call_rcu(). As such that is what I have updated the behavior to be.

-Subject: [PATCH] fib_trie: inflate/halve nodes in a more RCU friendly
- way
-
-This change pulls the node_set_parent functionality out of put_child_reorg
-and instead leaves that to the function to take care of as well. By doing
-this we can fully construct the new cluster of tnodes and all of the
-pointers out of it before we start routing pointers into it.
-
-I am suspecting this will likely fix some concurency issues though I don't
-have a good test to show as such.

-Subject: [PATCH] fib_trie: Remove checks for index >= tnode_child_length
- from tnode_get_child
-
-For some reason the compiler doesn't seem to understand that when we are in
-a loop that runs from tnode_child_length - 1 to 0 we don't expect the value
-of tn->bits to change. As such every call to tnode_get_child was rerunning
-tnode_chile_length which ended up consuming quite a bit of space in the
-resultant assembly code.
-
-I have gone though and verified that in all cases where tnode_get_child
-is used we are either winding though a fixed loop from tnode_child_length -
-1 to 0, or are in a fastpath case where we are verifying the value by
-either checking for any remaining bits after shifting index by bits and
-testing for leaf, or by using tnode_child_length.

-Subject: [PATCH] fib_trie: Add tracking value for suffix length
-
-This change adds a tracking value for the maximum suffix length of all
-prefixes stored in any given tnode. With this value we can determine if we
-need to backtrace or not based on if the suffix is greater than the pos
-value.
-
-By doing this we can reduce the CPU overhead for lookups in the local table
-as many of the prefixes there are 32b long and have a suffix length of 0
-meaning we can immediately backtrace to the root node without needing to
-test any of the nodes between it and where we ended up.

-Subject: [PATCH] fib_trie: Fix RCU bug and merge similar bits of inflate/halve
-
-This patch addresses two issues.
-
-The first issue is the fact that I believe I had the RCU freeing sequence
-slightly out of order. As a result we could get into an issue if a caller
-went into a child of a child of the new node, then backtraced into the to be
-freed parent, and then attempted to access a child of a child that may have
-been consumed in a resize of one of the new nodes children. To resolve this I
-have moved the resize after we have freed the oldtnode. The only side effect
-of this is that we will now be calling resize on more nodes in the case of
-inflate due to the fact that we don't have a good way to test to see if a
-full_tnode on the new node was there before or after the allocation. This
-should have minimal impact however since the node should already be
-correctly size so it is just the cost of calling should_inflate that we
-will be taking on the node which is only a couple of cycles.
-
-The second issue is the fact that inflate and halve were essentially doing
-the same thing after the new node was added to the trie replacing the old
-one. As such it wasn't really necessary to keep the code in both functions
-so I have split it out into two other functions, called replace and
-update_children.

-Subject: [PATCH] fib_trie: Fall back to slen update on inflate/halve failure
-
-This change corrects an issue where if inflate or halve fails we were
-exiting the resize function without at least updating the slen for the
-node. To correct this I have moved the update of max_size into the while
-loop so that it is only decremented on a successful call to either inflate
-or halve.

-Subject: [PATCH] fib_trie: Add collapse() and should_collapse() to resize
-
-This patch really does two things.
-
-First it pulls the logic for determining if we should collapse one node out
-of the tree and the actual code doing the collapse into a separate pair of
-functions. This helps to make the changes to these areas more readable.
-
-Second it encodes the upper 32b of the empty_children value onto the
-full_children value in the case of bits == KEYLENGTH. By doing this we are
-able to handle the case of a 32b node where empty_children would appear to
-be 0 when it was actually 1ul << 32.

-
-While doing further work on the fib_trie I noted a few items.
-
-First I was using calls that were far more complicated than they needed to
-be for determining when to push/pull the suffix length. I have updated the
-code to reflect the simplier logic.
-
-The second issue is that I realised we weren't necessarily handling the
-case of a leaf_info struct surviving a flush. I have updated the logic so
-that now we will call pull_suffix in the event of having a leaf info value
-left in the leaf after flushing it.

-Subject: [PATCH] pppoe: Use workqueue to die properly when a PADT is received
-
-When a PADT frame is received, the socket may not be in a good state to
-close down the PPP interface. The current implementation handles this by
-simply blocking all further PPP traffic, and hoping that the lack of traffic
-will trigger the user to investigate.
-
-Use schedule_work to get to a process context from which we clear down the
-PPP interface, in a fashion analogous to hangup on a TTY-based PPP
-interface. This causes pppd to disconnect immediately, and allows tools to
-take immediate corrective action.
-
-Note that pppd's rp_pppoe.so plugin has code in it to disable the session
-when it disconnects; however, as a consequence of this patch, the session is
-already disabled before rp_pppoe.so is asked to disable the session. The
-result is a harmless error message:
-
-Failed to disconnect PPPoE socket: 114 Operation already in progress
-
-This message is safe to ignore, as long as the error is 114 Operation
-already in progress; in that specific case, it means that the PPPoE session
-has already been disabled before pppd tried to disable it.

-Subject: [PATCH] ipv6: ip6_fragment: fix headroom tests and skb leak
-
-David Woodhouse reports skb_under_panic when we try to push ethernet
-header to fragmented ipv6 skbs:
-
- skbuff: skb_under_panic: text:c1277f1e len:1294 put:14 head:dec98000
- data:dec97ffc tail:0xdec9850a end:0xdec98f40 dev:br-lan
-[..]
-ip6_finish_output2+0x196/0x4da
-
-David further debugged this:
- [..] offending fragments were arriving here with skb_headroom(skb)==10.
- Which is reasonable, being the Solos ADSL card's header of 8 bytes
- followed by 2 bytes of PPP frame type.
-
-The problem is that if netfilter ipv6 defragmentation is used, skb_cow()
-in ip6_forward will only see reassembled skb.
-
-Therefore, headroom is overestimated by 8 bytes (we pulled fragment
-header) and we don't check the skbs in the frag_list either.
-
-We can't do these checks in netfilter defrag since outdev isn't known yet.
-
-Furthermore, existing tests in ip6_fragment did not consider the fragment
-or ipv6 header size when checking headroom of the fraglist skbs.
-
-While at it, also fix a skb leak on memory allocation -- ip6_fragment
-must consume the skb.
-
-I tested this e1000 driver hacked to not allocate additional headroom
-(we end up in slowpath, since LL_RESERVED_SPACE is 16).
-
-If 2 bytes of headroom are allocated, fastpath is taken (14 byte
-ethernet header was pulled, so 16 byte headroom available in all
-fragments).

-Subject: [PATCH] solos-pci: Increase headroom on received packets
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-A comment in include/linux/skbuff.h says that:
-
- * Various parts of the networking layer expect at least 32 bytes of
- * headroom, you should not reduce this.
-
-This was demonstrated by a panic when handling fragmented IPv6 packets:
-http://marc.info/?l=linux-netdev&m=144236093519172&w=2
-
-It's not entirely clear if that comment is still valid — and if it is,
-perhaps netif_rx() ought to be enforcing it with a warning.
-
-But either way, it is rather stupid from a performance point of view
-for us to be receiving packets into a buffer which doesn't have enough
-room to prepend an Ethernet header — it means that *every* incoming
-packet is going to be need to be reallocated. So let's fix that.

-
-Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support
-for LZO compression in regcache, but there were never any users added
-afterwards. Since LZO support itself has its own size, it currently is
-rather a deoptimization.
-
-So make it optional by introducing a symbol that can be selected by
-drivers wanting to make use of it.
-
-Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).

-I tried using google to find any users (even out-of-tree ones), but at
-best I found a single driver submission that was switched to RBTREE in
-subsequent resubmissions (MFD_SMSC).
-
-One could maybe also just drop the code because of no users for 5 years,
-but that would be up to the maintainer(s) to decide.

-> do you have an idea whats wrong?
-> 1) is it really needed, that we need space for creating dir "/overlay/work"?
-> 2) why does overlay need "/overlay/work/work"?
-
-The work directory is needed for atomic copy-up and similar. It is not actually
-necessary to mount a read-only overlay. Post 4.0 it is possible to mount the
-overlay without workdir (but even then it won't happen automatically in case the
-upper fs is full, so this should be fixed in the latest kernel too).
-
-Could you please try the following patch? If the workdir can't be created it
-will fall back to mounting the overlay read-only.
-
-Thanks,
-Miklos

-Subject: [PATCH] spi: Pump transfers inside calling context for spi_sync()
-
-If we are using the standard SPI message pump (which all drivers should be
-transitioning over to) then special case the message enqueue and instead of
-starting the worker thread to push messages to the hardware do so in the
-context of the caller if the controller is idle. This avoids a context
-switch in the common case where the controller has a single user in a
-single thread, for short PIO transfers there may be no need to context
-switch away from the calling context to complete the transfer.
-
-The code is a bit more complex than is desirable in part due to the need
-to handle drivers not using the standard queue and in part due to handling
-the various combinations of bus locking and asynchronous submission in
-interrupt context.
-
-It is still suboptimal since it will still wake the message pump for each
-transfer in order to schedule idling of the hardware and if multiple
-contexts are using the controller simultaneously a caller may end up
-pumping a message for some random other thread rather than for itself,
-and if the thread ends up deferring due to another context idling the
-hardware then it will just busy wait. It can, however, have the benefit
-of aggregating power up and down of the hardware when a caller performs
-a series of transfers back to back without any need for the use of
-spi_async().

-
-In order to avoid the situation where the kthread is waiting for another
-context to make the hardware idle let the message pump know if it's being
-called from the worker thread context and if it isn't then defer to the
-worker thread instead of idling the hardware immediately. This will ensure

-Subject: [PATCH] mm: remove gup_flags FOLL_WRITE games from __get_user_pages()
-
-[ Upstream commit 19be0eaffa3ac7d8eb6784ad9bdbc7d67ed8e619 ]
-
-This is an ancient bug that was actually attempted to be fixed once
-(badly) by me eleven years ago in commit 4ceb5db9757a ("Fix
-get_user_pages() race for write access") but that was then undone due to
-problems on s390 by commit f33ea7f404e5 ("fix get_user_pages bug").
-
-In the meantime, the s390 situation has long been fixed, and we can now
-fix it by checking the pte_dirty() bit properly (and do it better). The
-s390 dirty bit was implemented in abf09bed3cce ("s390/mm: implement
-software dirty bits") which made it into v3.9. Earlier kernels will
-have to look at the page state itself.
-
-Also, the VM has become more scalable, and what used a purely
-theoretical race back then has become easier to trigger.
-
-To fix it, we introduce a new internal FOLL_COW flag to mark the "yes,
-we already did a COW" rather than play racy games with FOLL_WRITE that
-is very fundamental, and then use the pte dirty flag to validate that
-the FOLL_COW flag is still valid.

-Subject: [PATCH] module_arch_freeing_init(): new hook for archs before module->module_init freed.
-
-Archs have been abusing module_free() to clean up their arch-specific
-allocations. Since module_free() is also (ab)used by BPF and trace code,
-let's keep it to simple allocations, and provide a hook called before
-that.
-
-This means that avr32, ia64, parisc and s390 no longer need to implement
-their own module_free() at all. avr32 doesn't need module_finalize()
-either.

-When an ethernet device is enslaved to a bridge, and the bridge STP

-
-This breaks control applications like WPA which maybe expecting to

-Subject: [PATCH] MIPS: UAPI: Ignore __arch_swab{16,32,64} when using MIPS16
-
-Some GCC versions (e.g. 4.8.3) can incorrectly inline a function with
-MIPS32 instructions into another function with MIPS16 code [1], causing
-the assembler to genereate incorrect binary code or fail right away
-complaining about unrecognized opcode.
-
-In the case of __arch_swab{16,32}, when inlined by the compiler with
-flags `-mips32r2 -mips16 -Os', the assembler can fail with the following
-error.
-
- {standard input}:79: Error: unrecognized opcode `wsbh $2,$2'
-
-For performance concerns and to workaround the issue already existing in
-older compilers, just ignore these 2 functions when compiling with
-mips16 enabled.
-
- [1] Inlining nomips16 function into mips16 function can result in
- undefined builtins, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55777

-Subject: [PATCH] cdc_ncm: Add support for moving NDP to end of NCM frame
-
-NCM specs are not actually mandating a specific position in the frame for
-the NDP (Network Datagram Pointer). However, some Huawei devices will
-ignore our aggregates if it is not placed after the datagrams it points
-to. Add support for doing just this, in a per-device configurable way.
-While at it, update NCM subdrivers, disabling this functionality in all of
-them, except in huawei_cdc_ncm where it is enabled instead.
-We aren't making any distinction between different Huawei NCM devices,
-based on what the vendor driver does. Standard NCM devices are left
-unaffected: if they are compliant, they should be always usable, still
-stay on the safe side.
-
-This change has been tested and working with a Huawei E3131 device (which
-works regardless of NDP position), a Huawei E3531 (also working both
-ways) and an E3372 (which mandates NDP to be after indexed datagrams).
-
-V1->V2:
-- corrected wrong NDP acronym definition
-- fixed possible NULL pointer dereference
-- patch cleanup
-V2->V3:
-- Properly account for the NDP size when writing new packets to SKB

-Subject: [PATCH] usb: ehci-orion: fix probe for !GENERIC_PHY
-
-Commit d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")
-added support for optional phys, but devm_phy_optional_get returns
--ENOSYS if GENERIC_PHY is not enabled.
-
-This causes probe failures, even when there are no phys specified:
-
-[ 1.443365] orion-ehci f1058000.usb: init f1058000.usb fail, -38
-[ 1.449403] orion-ehci: probe of f1058000.usb failed with error -38
-
-Similar to dwc3, treat -ENOSYS as no phy.
-
-Fixes: d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")

-Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
-
-including sysinfo.h from kernel.h makes no sense whatsoever,
-but removing it breaks glibc's userspace header,
-which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
-this seems to be a historical mistake.
-on musl, including any header that uses kernel.h directly or indirectly
-plus sys/sysinfo.h will produce a compile error due to redefinition of
-struct sysinfo from sys/sysinfo.h.
-so for now, only include it on glibc or when including from kernel
-in order not to break their headers.

-Message-Id: <1396868224-252888-2-git-send-email-manuel.lauss@gmail.com>
-
-This small patch makes the MIPS FPU emulator optional. The kernel
-kills float-users on systems without a hardware FPU by sending a SIGILL.
-
-Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
-optimizing for size).
-
-Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com>
----
-v4: rediffed because of patch 1/2, should now work with micromips as well
-v3: updated patch description with size savings.
-v2: incorporated changes suggested by Jonas Gorski
- force the fpu emulator on for micromips: relocating the parts
- of the mmips code in the emulator to other areas would be a
- much larger change; I went the cheap route instead with this.

-Subject: [PATCH 3/7] skb_reduce_truesize: helper function for shrinking skbs
- whenever needed
-
-On embedded devices in particular, large queues of small packets from the rx
-path with a large truesize can exist. Reducing their size can reduce
-memory pressure. skb_reduce_truesize is a helper function for doing this,
-when needed.

-Subject: [PATCH] Add support for MAP-E FMRs (mesh mode)
-
-MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
-between MAP CEs (mesh mode) without the need to forward such data to a
-border relay. This is similar to how 6rd works but for IPv4 over IPv6.

-Subject: [PATCH] ipv6: Fixed source specific default route handling.
-
-If there are only IPv6 source specific default routes present, the
-host gets -ENETUNREACH on e.g. connect() because ip6_dst_lookup_tail
-calls ip6_route_output first, and given source address any, it fails,
-and ip6_route_get_saddr is never called.
-
-The change is to use the ip6_route_get_saddr, even if the initial
-ip6_route_output fails, and then doing ip6_route_output _again_ after
-we have appropriate source address available.
-
-Note that this is '99% fix' to the problem; a correct fix would be to
-do route lookups only within addrconf.c when picking a source address,
-and never call ip6_route_output before source address has been
-populated.

-Subject: NET: skip GRO for foreign MAC addresses
-
-For network drivers using napi_gro_receive, packets are run through GRO,
-even when the destination MAC address does not match, and they're supposed
-to be delivered to another host behind a different bridge port.
-
-This can be very expensive, because for drivers without TSO or scatter-
-gather, this can only be undone by copying the skb and checksumming it
-again.
-
-To be able to track foreign MAC addresses in an inexpensive way, create
-a mask of changed bits in MAC addresses of upper devices. This allows
-handling VLANs and bridge devices with different addresses (as long as
-they are not too different).

-Subject: NET: add of_get_mac_address_mtd()
-
-Many embedded devices have information such as mac addresses stored inside mtd
-devices. This patch allows us to add a property inside a node describing a
-network interface. The new property points at a mtd partition with an offset
-where the mac address can be found.

- 8139cp: Fix DMA unmapping of transmitted buffers
-
- The low 16 bits of the 'opts1' field in the TX descriptor are supposed
- to still contain the buffer length when the descriptor is handed back to
- us. In practice, at least on my hardware, they don't. So stash the
- original value of the opts1 field and get the length to unmap from
- there.
-
- There are other ways we could have worked out the length, but I actually
- want a stash of the opts1 field anyway so that I can dump it alongside
- the contents of the descriptor ring when we suffer a TX timeout.

- We calculate the value of the opts1 descriptor field in three different

- 8139cp: Do not re-enable RX interrupts in cp_tx_timeout()
-
- If an RX interrupt was already received but NAPI has not yet run when
- the RX timeout happens, we end up in cp_tx_timeout() with RX interrupts
- already disabled. Blindly re-enabling them will cause an IRQ storm.
-
- (This is made particularly horrid by the fact that cp_interrupt() always
- returns that it's handled the interrupt, even when it hasn't actually
- done anything. If it didn't do that, the core IRQ code would have
- detected the storm and handled it, I'd have had a clear smoking gun
- backtrace instead of just a spontaneously resetting router, and I'd have
- at *least* two days of my life back. Changing the return value of
- cp_interrupt() will be argued about under separate cover.)
-
- Unconditionally leave RX interrupts disabled after the reset, and
- schedule NAPI to check the receive ring and re-enable them.

-Subject: [PATCH] libata: add ledtrig support
-To: linux-ide@vger.kernel.org,
- Tejun Heo <tj@kernel.org>
-
-This adds a LED trigger for each ATA port indicating disk activity.
-
-As this is needed only on specific platforms (NAS SoCs and such),
-these platforms should define ARCH_WANTS_LIBATA_LEDS if there
-are boards with LED(s) intended to indicate ATA disk activity and
-need the OS to take care of that.
-In that way, if not selected, LED trigger support not will be
-included in libata-core and both, codepaths and structures remain
-untouched.

-Subject: [PATCH] fq_codel: add batch ability to fq_codel_drop()
-
-In presence of inelastic flows and stress, we can call
-fq_codel_drop() for every packet entering fq_codel qdisc.
-
-fq_codel_drop() is quite expensive, as it does a linear scan
-of 4 KB of memory to find a fat flow.
-Once found, it drops the oldest packet of this flow.
-
-Instead of dropping a single packet, try to drop 50% of the backlog
-of this fat flow, with a configurable limit of 64 packets per round.
-
-TCA_FQ_CODEL_DROP_BATCH_SIZE is the new attribute to make this
-limit configurable.
-
-With this strategy the 4 KB search is amortized to a single cache line
-per drop [1], so fq_codel_drop() no longer appears at the top of kernel
-profile in presence of few inelastic flows.
-
-[1] Assuming a 64byte cache line, and 1024 buckets

-Subject: [PATCH] fq_codel: add memory limitation per queue
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-On small embedded routers, one wants to control maximal amount of
-memory used by fq_codel, instead of controlling number of packets or
-bytes, since GRO/TSO make these not practical.
-
-Assuming skb->truesize is accurate, we have to keep track of
-skb->truesize sum for skbs in queue.
-
-This patch adds a new TCA_FQ_CODEL_MEMORY_LIMIT attribute.
-
-I chose a default value of 32 MBytes, which looks reasonable even
-for heavy duty usages. (Prior fq_codel users should not be hurt
-when they upgrade their kernels)
-
-Two fields are added to tc_fq_codel_qd_stats to report :
- - Current memory usage
- - Number of drops caused by memory limits
-
-# tc qd replace dev eth1 root est 1sec 4sec fq_codel memory_limit 4M
-..
-# tc -s -d qd sh dev eth1
-qdisc fq_codel 8008: root refcnt 257 limit 10240p flows 1024
- quantum 1514 target 5.0ms interval 100.0ms memory_limit 4Mb ecn

-
-My prior attempt to fix the backlogs of parents failed.
-
-If we return NET_XMIT_CN, our parents wont increase their backlog,
-so our qdisc_tree_reduce_backlog() should take this into account.
-
-v2: Florian Westphal pointed out that we could drop the packet,
-so we need to save qdisc_pkt_len(skb) in a temp variable before
-calling fq_codel_drop()

-Subject: [PATCH] mtd: bcm47xxsflash: use ioremap_cache() instead of
- KSEG0ADDR()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Using KSEG0ADDR makes code highly MIPS dependent and not portable.
-Thanks to the fix a68f376 ("MIPS: io.h: Define `ioremap_cache'") we can
-use ioremap_cache which is generic and supported on MIPS as well now.
-
-KSEG0ADDR was translating 0x1c000000 into 0x9c000000. With ioremap_cache
-we use MIPS's __ioremap (and then remap_area_pages). This results in
-different address (e.g. 0xc0080000) but it still should be cached as
-expected and it was successfully tested with BCM47186B0.
-
-Other than that drivers/bcma/driver_chipcommon_sflash.c nicely setups a
-struct resource for access window, but we wren't using it. Use it now
-and drop duplicated info.

-Subject: [PATCH] mtd: add arch dependency for MTD_BCM47XXSFLASH symbol
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-We dropped strict MIPS dependency for bcm47xxsflash driver in:
-commit 5651d6aaf489 ("mtd: bcm47xxsflash: use ioremap_cache() instead of
-KSEG0ADDR()") but using ioremap_cache still limits building it to few
-selected architectures only.
-
-A recent commit 57d8f7dd2132 ("bcma: allow enabling serial flash support
-on non-MIPS SoCs") automatically dropped MIPS dependency for
-MTD_BCM47XXSFLASH which broke building e.g. on powerpc and cris.
-
-The bcma change is alright as it doesn't break building bcma code in any
-way. MTD_BCM47XXSFLASH on the other hand should be limited to archs
-which need it and can build it (by providing ioremap_cache).

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and uses
-this old ChipCommon-based flash access. Early tests resulted in flash
-corruptions that were tracked down to using cached MMIO for flash read
-access. Switch to ioremap_nocache conditionally to support BCM53573 and
-don't break performance on old MIPS devices.

-
-For reading flash content we use MMIO but it's possible to read only

-To support flash sizes bigger than 16 MiB implement indirect access

-Subject: [PATCH] mtd: bcm47xxpart: move TRX parsing code to separated function
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This change simplifies main parsing loop logic a bit. In future it may
-be useful for moving TRX support to separated module / parser (if we
-implement support for them at some point).
-Finally parsing TRX at the end puts us in a better position as we have
-better flash layout knowledge. It may be useful e.g. if it appears there
-is more than 1 TRX partition.

-Certain SPI controllers may provide accelerated hardware interface to

-performance. SPI core supports such devices with spi_flash_read() API.
-Call spi_flash_read(), if supported, to make use of such interface.

-
-Probe-mounting a volume too small for UBIFS results in kernel log
-polution which might irritate users.
-Address this by silencing errors which may happen during boot if the
-rootfs is e.g. squashfs (and thus rather small) stored on a UBI volume.

-Subject: netfilter: conntrack: cache route for forwarded connections
-
-... to avoid per-packet FIB lookup if possible.
-
-The cached dst is re-used provided the input interface
-is the same as that of the previous packet in the same direction.
-
-If not, the cached dst is invalidated.
-
-For ipv6 we also need to store sernum, else dst_check doesn't work,
-pointed out by Eric Dumazet.
-
-This should speed up forwarding when conntrack is already in use
-anyway, especially when using reverse path filtering -- active RPF
-enforces two FIB lookups for each packet.
-
-Before the routing cache removal this didn't matter since RPF was performed
-only when route cache didn't yield a result; but without route cache it
-comes at higher price.
-
-Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
-avoid holding on to dsts of 'frozen' conntracks.

-Subject: [PATCH] ovl: rename is_merge to is_lowest
-
-The 'is_merge' is an historical naming from when only a single lower layer
-could exist. With the introduction of multiple lower layers the meaning of
-this flag was changed to mean only the "lowest layer" (while all lower
-layers were being merged).
-
-So now 'is_merge' is inaccurate and hence renaming to 'is_lowest'

-Subject: [PATCH] ovl: override creds with the ones from the superblock mounter
-
-In user namespace the whiteout creation fails with -EPERM because the
-current process isn't capable(CAP_SYS_ADMIN) when setting xattr.
-
-A simple reproducer:
-
-$ mkdir upper lower work merged lower/dir
-$ sudo mount -t overlay overlay -olowerdir=lower,upperdir=upper,workdir=work merged
-$ unshare -m -p -f -U -r bash
-
-Now as root in the user namespace:
-
-\# touch merged/dir/{1,2,3} # this will force a copy up of lower/dir
-\# rm -fR merged/*
-
-This ends up failing with -EPERM after the files in dir has been
-correctly deleted:
-
-unlinkat(4, "2", 0) = 0
-unlinkat(4, "1", 0) = 0
-unlinkat(4, "3", 0) = 0
-close(4) = 0
-unlinkat(AT_FDCWD, "merged/dir", AT_REMOVEDIR) = -1 EPERM (Operation not
-permitted)
-
-Interestingly, if you don't place files in merged/dir you can remove it,
-meaning if upper/dir does not exist, creating the char device file works
-properly in that same location.
-
-This patch uses ovl_sb_creator_cred() to get the cred struct from the
-superblock mounter and override the old cred with these new ones so that
-the whiteout creation is possible because overlay is wrong in assuming that
-the creds it will get with prepare_creds will be in the initial user
-namespace. The old cap_raise game is removed in favor of just overriding
-the old cred struct.
-
-This patch also drops from ovl_copy_up_one() the following two lines:
-
-override_cred->fsuid = stat->uid;
-override_cred->fsgid = stat->gid;
-
-This is because the correct uid and gid are taken directly with the stat
-struct and correctly set with ovl_set_attr().

-Subject: [PATCH] ovl: proper cleanup of workdir
-
-When mounting overlayfs it needs a clean "work" directory under the
-supplied workdir.
-
-Previously the mount code removed this directory if it already existed and
-created a new one. If the removal failed (e.g. directory was not empty)
-then it fell back to a read-only mount not using the workdir.
-
-While this has never been reported, it is possible to get a non-empty
-"work" dir from a previous mount of overlayfs in case of crash in the
-middle of an operation using the work directory.
-
-In this case the left over state should be discarded and the overlay
-filesystem will be consistent, guaranteed by the atomicity of operations on
-moving to/from the workdir to the upper layer.
-
-This patch implements cleaning out any files left in workdir. It is
-implemented using real recursion for simplicity, but the depth is limited
-to 2, because the worst case is that of a directory containing whiteouts
-under "work".

-This patchs adds O_TMPFILE support to UBIFS.
-A temp file is a reference to an unlinked inode, a user

-
-Adds RENAME_EXCHANGE to UBIFS, the operation itself
-is completely disjunct from a regular rename() that's
-why we dispatch very early in ubifs_reaname().
-
-RENAME_EXCHANGE used by the renameat2() system call
-allows the caller to exchange two paths atomically.

-Subject: [PATCH] ubifs: Use dirty_writeback_interval value for wbuf timer
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Right now wbuf timer has hardcoded timeouts and there is no place for
-manual adjustments. Some projects / cases many need that though. Few
-file systems allow doing that by respecting dirty_writeback_interval
-that can be set using sysctl (dirty_writeback_centisecs).
-
-Lowering dirty_writeback_interval could be some way of dealing with user
-space apps lacking proper fsyncs. This is definitely *not* a perfect
-solution but we don't have ideal (user space) world. There were already
-advanced discussions on this matter, mostly when ext4 was introduced and
-it wasn't behaving as ext3. Anyway, the final decision was to add some
-hacks to the ext4, as trying to fix whole user space or adding new API
-was pointless.
-
-We can't (and shouldn't?) just follow ext4. We can't e.g. sync on close
-as this would cause too many commits and flash wearing. On the other
-hand we still should allow some trade-off between -o sync and default
-wbuf timeout. Respecting dirty_writeback_interval should allow some sane
-cutomizations if used warily.

-Subject: [PATCH] softirq: let ksoftirqd do its job
-
-A while back, Paolo and Hannes sent an RFC patch adding threaded-able
-napi poll loop support : (https://patchwork.ozlabs.org/patch/620657/)
-
-The problem seems to be that softirqs are very aggressive and are often
-handled by the current process, even if we are under stress and that
-ksoftirqd was scheduled, so that innocent threads would have more chance
-to make progress.
-
-This patch makes sure that if ksoftirq is running, we let it
-perform the softirq work.
-
-Jonathan Corbet summarized the issue in https://lwn.net/Articles/687617/
-
-Tested:
-
- - NIC receiving traffic handled by CPU 0
- - UDP receiver running on CPU 0, using a single UDP socket.
- - Incoming flood of UDP packets targeting the UDP socket.
-
-Before the patch, the UDP receiver could almost never get cpu cycles and
-could only receive ~2,000 packets per second.
-
-After the patch, cpu cycles are split 50/50 between user application and
-ksoftirqd/0, and we can effectively read ~900,000 packets per second,
-a huge improvement in DOS situation. (Note that more packets are now
-dropped by the NIC itself, since the BH handlers get less cpu cycles to
-drain RX ring buffer)
-
-Since the load runs in well identified threads context, an admin can
-more easily tune process scheduling parameters if needed.

-Subject: [PATCH] net: bgmac: clarify CONFIG_BCMA dependency
-
-The bgmac driver depends on BCMA_HOST_SOC, which is only used
-when CONFIG_BCMA is enabled. However, it is a bool option and can
-be set when CONFIG_BCMA=m, and then bgmac can be built-in, leading
-to an obvious link error:
-
-drivers/built-in.o: In function `bgmac_init':
-:(.init.text+0x7f2c): undefined reference to `__bcma_driver_register'
-drivers/built-in.o: In function `bgmac_exit':
-:(.exit.text+0x110a): undefined reference to `bcma_driver_unregister'
-
-To avoid this case, we need to depend on both BCMA and BCMA_SOC,
-as this patch does. I'm also trying to make the dependency more
-readable by splitting it into three lines, and adding a COMPILE_TEST
-alternative so we can test-build it in all configurations that
-support BCMA.
-
-The added dependency on FIXED_PHY addresses a related issue where
-we cannot call fixed_phy_register() when CONFIG_FIXED_PHY=m and
-CONFIG_BGMAC=y.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Only core revisions older than 4 use BGMAC_CMDCFG_SR_REV0. This mainly
-fixes support for BCM4708A0KF SoCs with Ethernet core rev 5 (it means
-only some devices as most of BCM4708A0KF-s got core rev 4).
-This was tested for regressions on BCM47094 which doesn't seem to care
-which bit gets used.

-Subject: [PATCH 1/2] net: ethernet: bgmac: use phydev from struct net_device
-
-The private structure contain a pointer to phydev, but the structure
-net_device already contain such pointer. So we can remove the pointer
-phydev in the private structure, and update the driver to use the
-one contained in struct net_device.

-Subject: [PATCH 1/5] net: ethernet: bgmac: change bgmac_* prints to dev_*
- prints
-
-The bgmac_* print wrappers call dev_* prints with the dev pointer from
-the bcma core. In anticipation of removing the bcma requirement for
-this driver, these must be changed to not reference that struct. So,
-simply change all of the bgmac_* prints to their dev_* counterparts. In
-some cases netdev_* prints are more appropriate, so change those as
-well.

-Subject: [PATCH 3/5] net: ethernet: bgmac: move BCMA MDIO Phy code into a
- separate file
-
-Move the BCMA MDIO phy into a separate file, as it is very tightly
-coupled with the BCMA bus. This will help with the upcoming BCMA
-removal from the bgmac driver. Optimally, this should be moved into
-phy drivers, but it is too tightly coupled with the bgmac driver to
-effectively move it without more changes to the driver.
-
-Note: the phy_reset was intentionally removed, as the mdio phy subsystem
-automatically resets the phy if a reset function pointer is present. In
-addition to the moving of the driver, this reset function is added.

-Subject: [PATCH 4/5] net: ethernet: bgmac: convert to feature flags
-
-The bgmac driver is using the bcma provides device ID and revision, as
-well as the SoC ID and package, to determine which features are
-necessary to enable, reset, etc in the driver. In anticipation of
-removing the bcma requirement for this driver, these must be changed to
-not reference that struct. In place of that, each "feature" has been
-given a flag, and the flags are enabled for their respective device and
-SoC.

-Subject: [PATCH 5/5] net: ethernet: bgmac: Add platform device support
-
-The bcma portion of the driver has been split off into a bcma specific
-driver. This has been mirrored for the platform driver. The last
-references to the bcma core struct have been changed into a generic
-function call. These function calls are wrappers to either the original
-bcma code or new platform functions that access the same areas via MMIO.
-This necessitated adding function pointers for both platform and bcma to
-hide which backend is being used from the generic bgmac code.

-Subject: [PATCH] net: bgmac: support Ethernet core on BCM53573 SoCs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and can
-be found in two packages (versions): BCM53573 and BCM47189. It shares
-some code with the Northstar family, but also requires some new quirks.
-
-First of all there can be up to 2 Ethernet cores on this SoC. If that is
-the case, they are connected to two different switch ports allowing some
-more complex/optimized setups. It seems the second unit doesn't come
-fully configured and requires some IRQ quirk.
-
-Other than that only the first core is connected to the PHY. For the
-second one we have to register fixed PHY (similarly to the Northstar),
-otherwise generic PHY driver would get some invalid info.
-
-This has been successfully tested on Tenda AC9 (BCM47189B0).

-
-This fixes regression introduced by patch adding feature flags. It was
-already reported and patch followed (it got accepted) but it appears it
-was incorrect. Instead of fixing reversed condition it broke a good one.
-
-This patch was verified to actually fix SoC hanges caused by bgmac on
-BCM47186B0.
-
-Fixes: db791eb2970b ("net: ethernet: bgmac: convert to feature flags")

-
-This patch adds devm_alloc_etherdev_mqs function and devm_alloc_etherdev
-macro. These can be used for simpler netdev allocation without having to
-care about calling free_netdev.
-
-Thanks to this change drivers, their error paths and removal paths may
-get simpler by a bit.

-Subject: [PATCH 1/3] net: bgmac: allocate struct bgmac just once & don't copy
- it
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-So far were were allocating struct bgmac in 3 places: platform code,
-bcma code and shared bgmac_enet_probe function. The reason for this was
-bgmac_enet_probe:
-1) Requiring early-filled struct bgmac
-2) Calling alloc_etherdev on its own in order to use netdev_priv later
-
-This solution got few drawbacks:
-1) Was duplicating allocating code
-2) Required copying early-filled struct
-3) Resulted in platform/bcma code having access only to unused struct
-
-Solve this situation by simply extracting some probe code into the new
-bgmac_alloc function.

-Adding struct bcma_mdio was a workaround for bcma code not having access

-struct we can just use it internally in bcma code.
-
-This simplifies code & allows access to all bgmac driver details from

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This adds support for using bgmac with PHYs supported by standalone PHY
-drivers. Having any PHY initialization in bgmac is hacky and shouldn't
-be extended but rather removed if anyone has hardware to test it.

- v4.10-rc1
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This includes following upstream commits:
-5519da874ad0 net: phy: broadcom: Move bcm54xx_auxctl_{read, write} to common library
-b14995ac2527 net: phy: broadcom: Add BCM54810 PHY entry
-5b4e29005123 net: phy: broadcom: add bcm54xx_auxctl_read
-d92ead16be40 net: phy: broadcom: Add support for BCM54612E
-3cf25904fe46 net: phy: broadcom: Update Auxiliary Control Register macros
-
-Other commits were skipped as they depend on other changes like
-ETHTOOL_PHY_DOWNSHIFT & DOWNSHIFT_DEV_DISABLE and new APIs like
-get_sset_count.
-
-One exception was picking new regs from commit d06f78c4232d ("net: phy:
-broadcom: Add support code for downshift/Wirespeed").

-Subject: [PATCH] spi: introduce accelerated read support for spi flash devices
-
-In addition to providing direct access to SPI bus, some spi controller
-hardwares (like ti-qspi) provide special port (like memory mapped port)
-that are optimized to improve SPI flash read performance.
-This means the controller can automatically send the SPI signals
-required to read data from the SPI flash device.
-For this, SPI controller needs to know flash specific information like
-read command to use, dummy bytes and address width.
-
-Introduce spi_flash_read() interface to support accelerated read
-over SPI flash devices. SPI master drivers can implement this callback to
-support interfaces such as memory mapped read etc. m25p80 flash driver
-and other flash drivers can call this make use of such interfaces. The
-interface should only be used with SPI flashes and cannot be used with
-other SPI devices.

-Subject: [PATCH] USB: core: let USB device know device node
-
-Although most of USB devices are hot-plug's, there are still some devices
-are hard wired on the board, eg, for HSIC and SSIC interface USB devices.
-If these kinds of USB devices are multiple functions, and they can supply
-other interfaces like i2c, gpios for other devices, we may need to
-describe these at device tree.
-
-In this commit, it uses "reg" in dts as physical port number to match
-the phyiscal port number decided by USB core, if they are the same,
-then the device node is for the device we are creating for USB core.

-+Generic USB Device Properties
-+
-+Usually, we only use device tree for hard wired USB device.
-+The reference binding doc is from:
-+http://www.firmware.org/1275/bindings/usb/usb-1_0.ps
-+
-+Required properties:
-+- compatible: usbVID,PID. The textual representation of VID, PID shall
-+ be in lower case hexadecimal with leading zeroes suppressed. The
-+ other compatible strings from the above standard binding could also
-+ be used, but a device adhering to this binding may leave out all except
-+ for usbVID,PID.
-+- reg: the port number which this device is connecting to, the range
-+ is 1-31.
-+
-+Example:
-+
-+&usb1 {
-+ status = "okay";
-+
-+ #address-cells = <1>;
-+ #size-cells = <0>;
-+
-+ hub: genesys@1 {
-+ compatible = "usb5e3,608";

-Subject: [PATCH] usb/core: usb_alloc_dev(): fix setting of ->portnum
-
-With commit 69bec7259853 ("USB: core: let USB device know device node"),
-the port1 argument of usb_alloc_dev() gets overwritten as follows:
-
- ... usb_alloc_dev(..., unsigned port1)
- {
- ...
- if (!parent->parent) {
- port1 = usb_hcd_find_raw_port_number(..., port1);
- }
- ...
- }
-
-Later on, this now overwritten port1 gets assigned to ->portnum:
-
- dev->portnum = port1;
-
-However, since xhci_find_raw_port_number() isn't idempotent, the
-aforementioned commit causes a number of KASAN splats like the following:
-
- BUG: KASAN: slab-out-of-bounds in xhci_find_raw_port_number+0x98/0x170

- xhci_hcd 0000:00:14.0: ERROR: unexpected setup address command completion
- code 0x11.
- usb 4-3: device not accepting address 2, error -22
-
-Fix this by not overwriting the port1 argument in usb_alloc_dev(), but
-storing the raw port number as required by OF in an additional variable,
-raw_port.

-Subject: [PATCH] clk: Add {devm_}clk_hw_{register,unregister}() APIs
-
-We've largely split the clk consumer and provider APIs along
-struct clk and struct clk_hw, but clk_register() still returns a
-struct clk pointer for each struct clk_hw that's registered.
-Eventually we'd like to only allocate struct clks when there's a
-user, because struct clk is per-user now, so clk_register() needs
-to change.
-
-Let's add new APIs to register struct clk_hws, but this time
-we'll hide the struct clk from the caller by returning an int
-error code. Also add an unregistration API that takes the clk_hw
-structure that was passed to the registration API. This way
-provider drivers never have to deal with a struct clk pointer
-unless they're using the clk consumer APIs.

-Subject: [PATCH] clk: Add clk_hw OF clk providers
-
-Now that we have a clk registration API that doesn't return
-struct clks, we need to have some way to hand out struct clks via
-the clk_get() APIs that doesn't involve associating struct clk
-pointers with an OF node. Currently we ask the OF provider to
-give us a struct clk pointer for some clkspec, turn that struct
-clk into a struct clk_hw and then allocate a new struct clk to
-return to the caller.
-
-Let's add a clk_hw based OF provider hook that returns a struct
-clk_hw directly, so that we skip the intermediate step of
-converting from struct clk to struct clk_hw. Eventually when
-we've converted all OF clk providers to struct clk_hw based APIs
-we can remove the struct clk based ones.
-
-It should also be noted that we change the onecell provider to
-have a flex array instead of a pointer for the array of clk_hw
-pointers. This allows providers to allocate one structure of the
-correct length in one step instead of two.

-Subject: [PATCH] usb: core: Introduce a USB port LED trigger
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This commit adds a new trigger responsible for turning on LED when USB
-device gets connected to the selected USB port. This can can useful for
-various home routers that have USB port(s) and a proper LED telling user
-a device is connected.
-
-The trigger gets its documentation file but basically it just requires
-enabling it and selecting USB ports (e.g. echo 1 > ports/usb1-1).
-
-There was a long discussion on design of this driver. Its current state
-is a result of picking them most adjustable solution as others couldn't
-handle all cases.
-
-1) It wasn't possible for the driver to register separated trigger for
- each USB port. Some physical USB ports are handled by more than one
- controller and so by more than one USB port. E.g. USB 2.0 physical
- port may be handled by OHCI's port and EHCI's port.
- It's also not possible to assign more than 1 trigger to a single LED
- and implementing such feature would be tricky due to syncing triggers
- and sysfs conflicts with old triggers.
-
-2) Another idea was to register trigger per USB hub. This wouldn't allow
- handling devices with multiple USB LEDs and controllers (hubs)
- controlling more than 1 physical port. It's common for hubs to have
- few ports and each may have its own LED.
-
-This final trigger is highly flexible. It allows selecting any USB ports
-for any LED. It was also modified (comparing to the initial version) to
-allow choosing ports rather than having user /guess/ proper names. It
-was successfully tested on SmartRG SR400ac which has 3 USB LEDs,
-2 physical ports and 3 controllers.
-
-It was noted USB subsystem already has usb-gadget and usb-host triggers
-but they are pretty trivial ones. They indicate activity only and can't
-have ports specified.
-
-In future it may be good idea to consider adding activity support to
-usbport as well. This should allow switching to this more generic driver
-and maybe marking old ones as obsolete.
-This can be implemented with another sysfs file for setting mode. The
-default mode wouldn't change so there won't be ABI breakage and so such
-feature can be safely implemented later.
-
-There was also an idea of supporting other devices (PCI, SDIO, etc.) but
-as this driver already contains some USB specific code (and will get
-more) these should be probably separated drivers (triggers).

-+USB port LED trigger
-+====================
-+
-+This LED trigger can be used for signalling to the user a presence of USB device
-+in a given port. It simply turns on LED when device appears and turns it off
-+when it disappears.
-+
-+It requires selecting USB ports that should be observed. All available ones are
-+listed as separated entries in a "ports" subdirectory. Selecting is handled by
-+echoing "1" to a chosen port.
-+
-+Please note that this trigger allows selecting multiple USB ports for a single
-+LED. This can be useful in two cases:
-+
-+1) Device with single USB LED and few physical ports
-+
-+In such a case LED will be turned on as long as there is at least one connected
-+USB device.
-+
-+2) Device with a physical port handled by few controllers
-+
-+Some devices may have one controller per PHY standard. E.g. USB 3.0 physical
-+port may be handled by ohci-platform, ehci-platform and xhci-hcd. If there is
-+only one LED user will most likely want to assign ports from all 3 hubs.
-+
-+
-+This trigger can be activated from user space on led class devices as shown
-+below:
-+
-+ echo usbport > trigger
-+
-+This adds sysfs attributes to the LED that are documented in:
-+Documentation/ABI/testing/sysfs-class-led-trigger-usbport
-+
-+Example use-case:
-+
-+ echo usbport > trigger
-+ echo 1 > ports/usb1-port1
-+ echo 1 > ports/usb2-port1
-+ cat ports/usb1-port1
-+ echo 0 > ports/usb1-port1

-Subject: [PATCH] leds: leds-gpio: Set of_node for created LED devices
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-When working with Device Tree we iterate over children of "gpio-leds"
-compatible node and create LED device for each of them. We take care of
-all common DT properties (label, default trigger, state, etc.), however
-some triggers may want to support more of them.
-
-It could be useful for timer trigger to support setting delay on/off
-values with Device Tree property. Or for transient trigger to support
-e.g. duration property.
-
-We obviously should handle such properties in triggers, not in generic
-code. To let trigger drivers read properties from DT node we need to set
-of_node to point the relevant node. This change allows using all kind of
-of helpers in e.g. "activate" callbacks.

-Subject: [PATCH] regmap: make LZO cache optional
-
-Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support
-for LZO compression in regcache, but there were never any users added
-afterwards. Since LZO support itself has its own size, it currently is
-rather a deoptimization.
-
-So make it optional by introducing a symbol that can be selected by
-drivers wanting to make use of it.
-
-Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).

-I tried using google to find any users (even out-of-tree ones), but at
-best I found a single driver submission that was switched to RBTREE in
-subsequent resubmissions (MFD_SMSC).
-
-One could maybe also just drop the code because of no users for 5 years,
-but that would be up to the maintainer(s) to decide.

-Subject: [PATCH] MIPS: c-r4k: Use IPI calls for CM indexed cache ops
-
-The Coherence Manager (CM) can propagate address-based ("hit") cache
-operations to other cores in the coherent system, alleviating software
-of the need to use IPI calls, however indexed cache operations are not
-propagated since doing so makes no sense for separate caches.
-
-r4k_on_each_cpu() previously had a special case for CONFIG_MIPS_MT_SMP,
-intended to avoid the IPIs when the only other CPUs in the system were
-other VPEs in the same core, and hence sharing the same caches. This was
-changed by commit cccf34e9411c ("MIPS: c-r4k: Fix cache flushing for MT
-cores") to apparently handle multi-core multi-VPE systems, but it
-focussed mainly on hit cache ops, so the IPI calls were still disabled
-entirely for CM systems.
-
-This doesn't normally cause problems, but tests can be written to hit
-these corner cases by using multiple threads, or changing task
-affinities to force the process to migrate cores. For example the
-failure of mprotect RW->RX to globally sync icaches (via
-flush_cache_range) can be detected by modifying and mprotecting a code
-page on one core, and migrating to a different core to execute from it.
-
-Most of the functions called by r4k_on_each_cpu() perform cache
-operations exclusively with a single addressing-type (virtual address vs
-indexed), so add a type argument and modify the callers to pass in
-R4K_USER (user virtual addressing), R4K_KERN (global kernel virtual
-addressing) or R4K_INDEX (index into cache).
-
-local_r4k_flush_icache_range() is split up, to allow it to be called
-from the rest of the kernel, or from r4k_flush_icache_range() where it
-will choose either indexed or hit cache operations based on the size of
-the range and the cache sizes.
-
-local_r4k_flush_kernel_vmap_range() is split into two functions, each of
-which uses cache operations with a single addressing-type, with
-r4k_flush_kernel_vmap_range() making the decision whether to use indexed
-cache ops or not.

-Subject: [PATCH] MIPS: store the appended dtb address in a variable
-
-Instead of rewriting the arguments to match the UHI spec, store the
-address of a appended or UHI supplied dtb in fw_supplied_dtb.
-
-That way the original bootloader arugments are kept intact while still
-making the use of an appended dtb invisible for mach code.
-
-Mach code can still find out if it is an appended dtb by comparing
-fw_arg1 with fw_supplied_dtb.

-Subject: [PATCH] MIPS: c-r4k: Fix size calc when avoiding IPIs for small
- icache flushes
-
-Commit f70ddc07b637 ("MIPS: c-r4k: Avoid small flush_icache_range SMP
-calls") adds checks to force use of hit-type cache ops for small icache
-flushes where they are globalised & index-type cache ops aren't, in
-order to avoid the overhead of IPIs in those cases. However it
-calculated the size of the region being flushed incorrectly, subtracting
-the end address from the start address rather than the reverse. This
-would have led to an overflow with size wrapping round to some large
-value, and likely to the special case for avoiding IPIs not actually
-being hit.

-
-As it was discussed quite some time ago (see
-https://lkml.org/lkml/2015/11/5/862) it's a good practice to add
-"model" property in .dts. Moreover as per ePAPR "model" property is
-required and should look like "manufacturer,model" so we do here.

-An rt288x (ralink) based router (Belkin F5D8235 v1) does not boot with any
-kernel beyond version 4.3 resulting in:

-
-This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
-page_to_pfn anymore.
-
-The following output was generated with two hacked in printk statements:
-
-printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
-(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
- if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
- mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
-printk("after %p\n", mem_map);
-
-Output:
-
-[ 0.000000] before 8861b280 vs. 8861b280 or 8851b280
-[ 0.000000] after 8851b280
-
-As seen in the first line mem_map with subtraction of offset does not equal the
-mem_map after subtraction of ARCH_PFN_OFFSET.
-
-After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
-previously calculated offset is zero for the named platform it is able to boot
-4.4 and 4.9-rc7 again.

-When an ethernet device is enslaved to a bridge, and the bridge STP

-This breaks control applications like WPA which maybe expecting to

-Subject: [PATCH] MIPS: partially inline dma ops
-
-Several DMA ops are no-op on many platforms, and the indirection through
-the mips_dma_map_ops function table is causing the compiler to emit
-unnecessary code.
-
-Inlining visibly improves network performance in my tests (on a 24Kc
-based system), and also slightly reduces code size of a few drivers.

-Subject: [PATCH 2/3] mtd: part: add generic parsing of linux,part-probe
-
-This moves the linux,part-probe device tree parsing code from
-physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
-providing a reference to their device tree node in struct
-mtd_part_parser_data.

-Subject: [PATCH] usb: gadget: net2280: add USB2380 support
-
-The PLX USB2380 is a PCIe version of the NET2280 and behaves more like the
-USB338x but without the USB3.0 superspeed support.
-
-This was tested with g_ether, g_serial, g_mass_storage on a Gateworks
-Ventana GW2383.

-Subject: [PATCH] Revert "bcma: init serial console directly from ChipCommon
- code"
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This reverts commit 4c81acab3816 ("bcma: init serial console directly
-from ChipCommon code") as it broke IRQ assignment. Getting IRQ with
-bcma_core_irq helper on SoC requires MIPS core to be set. It happens
-*after* ChipCommon initialization so we can't do this so early.
-
-This fixes a user reported regression. It wasn't critical as serial was
-still somehow working but lack of IRQs was making in unreliable.
-
-Fixes: 4c81acab3816 ("bcma: init serial console directly from ChipCommon code")
-Reported-by: Felix Fietkau <nbd@nbd.name>

-Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
-
-including sysinfo.h from kernel.h makes no sense whatsoever,
-but removing it breaks glibc's userspace header,
-which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
-this seems to be a historical mistake.
-on musl, including any header that uses kernel.h directly or indirectly
-plus sys/sysinfo.h will produce a compile error due to redefinition of
-struct sysinfo from sys/sysinfo.h.
-so for now, only include it on glibc or when including from kernel
-in order not to break their headers.

-
-Musl provides the same structs as glibc, but does not provide a define to
-allow its detection. Since the absence of __GLIBC__ also can mean that it
-is included from the kernel, change the __GLIBC__ detection to
-!__KERNEL__, which should always be true when included from userspace.

-Message-Id: <1396868224-252888-2-git-send-email-manuel.lauss@gmail.com>
-
-This small patch makes the MIPS FPU emulator optional. The kernel
-kills float-users on systems without a hardware FPU by sending a SIGILL.
-
-Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
-optimizing for size).
-
-Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com>
----
-v4: rediffed because of patch 1/2, should now work with micromips as well
-v3: updated patch description with size savings.
-v2: incorporated changes suggested by Jonas Gorski
- force the fpu emulator on for micromips: relocating the parts
- of the mmips code in the emulator to other areas would be a
- much larger change; I went the cheap route instead with this.

-Subject: [PATCH 1/2] openwrt: arc - remove dependency on DEVTMPFS
-
-OpenWRT builds initramfs so that it doesn't require DEVTMPFS so dropping
-this dependency. That helps to escape 2 separate kernel rebuilds with
-and without initramfs.
-
-2 builds happen because OpenWRT first builds kernel and later modules.
-When building entire kernel with simple "make" INITRAMFS sets to a real
-value and so was triggering DEVTMPFS selection. Then when building only
-modules with "make modules" command INITRAMFS is zeroed and so kernel
-config was changing that lead to full kernel rebuild.

-This change allows OpenWRT to patch resulting kernel binary with
-external .dtb.
-
-That allows us to re-use exactky the same vmlinux on different boards
-given its ARC core configurations match (at least cache line sizes etc).
-
-""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
-.dtb right after it, keeping the string in place.

-Subject: [PATCH] Add support for MAP-E FMRs (mesh mode)
-
-MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
-between MAP CEs (mesh mode) without the need to forward such data to a
-border relay. This is similar to how 6rd works but for IPv4 over IPv6.

-Subject: [PATCH 1/2] ipv6: allow rejecting with "source address failed policy"
-
-RFC6204 L-14 requires rejecting traffic from invalid addresses with
-ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
-egress policy) on the LAN side, so add an appropriate rule for that.

-Subject: NET: skip GRO for foreign MAC addresses
-
-For network drivers using napi_gro_receive, packets are run through GRO,
-even when the destination MAC address does not match, and they're supposed
-to be delivered to another host behind a different bridge port.
-
-This can be very expensive, because for drivers without TSO or scatter-
-gather, this can only be undone by copying the skb and checksumming it
-again.
-
-To be able to track foreign MAC addresses in an inexpensive way, create
-a mask of changed bits in MAC addresses of upper devices. This allows
-handling VLANs and bridge devices with different addresses (as long as
-they are not too different).

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The driver of course "knows" that the chip's reset signal is active low,
-so it drives the GPIO to 0 to reset the PHY and to 1 otherwise; however
-all this will only work iff the GPIO is specified as active-high in the
-device tree! I think both the driver and the device trees (if there are
-any -- I was unable to find them) need to be fixed in this case...

-Subject: [PATCH] net: phy: at803x: Request 'reset' GPIO only for AT8030 PHY
-
-This removes the dependency on GPIOLIB for non faulty PHYs.
-
-Indeed, without this patch, if GPIOLIB is not selected
-devm_gpiod_get_optional() will return -ENOSYS and the driver probe
-call will fail, regardless of the actual PHY hardware.
-
-Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035),
-only AT8030 presents the issues that commit 13a56b449325 ("net: phy:
-at803x: Add support for hardware reset") attempts to work-around by
-using a 'reset' GPIO line.
-
-Hence, only AT8030 should depend on GPIOLIB operating properly.
-
-Fixes: 13a56b449325 ("net: phy: at803x: Add support for hardware reset")

- link change
-
-Commit 13a56b44 ("at803x: Add support for hardware reset") added a
-work-around for a hardware bug on the AT8030. However, the work-around
-was being called for all 803x PHYs, even those that don't need it.
-Function at803x_link_change_notify() checks to make sure that it only
-resets the PHY on the 8030, but it makes more sense to not call that
-function at all if it isn't needed.

-There're some discussions in mailing lists proposing to disable
-that particular check alltogether and magically all seem to work
-fine with muted warning.
-
-Anyways new thread on that regard could be found here:
-http://lists.infradead.org/pipermail/linux-snps-arc/2016-July/001310.html
-
-Let's see what comes out of that new discussion, hopefully patching
-of generic USB stuff won't be required then.

-Subject: [PATCH] libata: add ledtrig support
-To: linux-ide@vger.kernel.org,
- Tejun Heo <tj@kernel.org>
-
-This adds a LED trigger for each ATA port indicating disk activity.
-
-As this is needed only on specific platforms (NAS SoCs and such),
-these platforms should define ARCH_WANTS_LIBATA_LEDS if there
-are boards with LED(s) intended to indicate ATA disk activity and
-need the OS to take care of that.
-In that way, if not selected, LED trigger support not will be
-included in libata-core and both, codepaths and structures remain
-untouched.

-Subject: netfilter: conntrack: cache route for forwarded connections
-
-... to avoid per-packet FIB lookup if possible.
-
-The cached dst is re-used provided the input interface
-is the same as that of the previous packet in the same direction.
-
-If not, the cached dst is invalidated.
-
-For ipv6 we also need to store sernum, else dst_check doesn't work,
-pointed out by Eric Dumazet.
-
-This should speed up forwarding when conntrack is already in use
-anyway, especially when using reverse path filtering -- active RPF
-enforces two FIB lookups for each packet.
-
-Before the routing cache removal this didn't matter since RPF was performed
-only when route cache didn't yield a result; but without route cache it
-comes at higher price.
-
-Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
-avoid holding on to dsts of 'frozen' conntracks.

-Subject: [PATCH] bridge: multicast to unicast
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Implements an optional, per bridge port flag and feature to deliver
-multicast packets to any host on the according port via unicast
-individually. This is done by copying the packet per host and
-changing the multicast destination MAC to a unicast one accordingly.
-
-multicast-to-unicast works on top of the multicast snooping feature of
-the bridge. Which means unicast copies are only delivered to hosts which
-are interested in it and signalized this via IGMP/MLD reports
-previously.
-
-This feature is intended for interface types which have a more reliable
-and/or efficient way to deliver unicast packets than broadcast ones
-(e.g. wifi).
-
-However, it should only be enabled on interfaces where no IGMPv2/MLDv1
-report suppression takes place. This feature is disabled by default.
-
-The initial patch and idea is from Felix Fietkau.

-Subject: [PATCH] net: add devm version of alloc_etherdev_mqs function
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This patch adds devm_alloc_etherdev_mqs function and devm_alloc_etherdev
-macro. These can be used for simpler netdev allocation without having to
-care about calling free_netdev.
-
-Thanks to this change drivers, their error paths and removal paths may
-get simpler by a bit.

-Subject: [PATCH] ubifs: Use dirty_writeback_interval value for wbuf timer
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Right now wbuf timer has hardcoded timeouts and there is no place for
-manual adjustments. Some projects / cases many need that though. Few
-file systems allow doing that by respecting dirty_writeback_interval
-that can be set using sysctl (dirty_writeback_centisecs).
-
-Lowering dirty_writeback_interval could be some way of dealing with user
-space apps lacking proper fsyncs. This is definitely *not* a perfect
-solution but we don't have ideal (user space) world. There were already
-advanced discussions on this matter, mostly when ext4 was introduced and
-it wasn't behaving as ext3. Anyway, the final decision was to add some
-hacks to the ext4, as trying to fix whole user space or adding new API
-was pointless.
-
-We can't (and shouldn't?) just follow ext4. We can't e.g. sync on close
-as this would cause too many commits and flash wearing. On the other
-hand we still should allow some trade-off between -o sync and default
-wbuf timeout. Respecting dirty_writeback_interval should allow some sane
-cutomizations if used warily.

-Subject: [PATCH] mtd: bcm47xxpart: move TRX parsing code to separated function
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This change simplifies main parsing loop logic a bit. In future it may
-be useful for moving TRX support to separated module / parser (if we
-implement support for them at some point).
-Finally parsing TRX at the end puts us in a better position as we have
-better flash layout knowledge. It may be useful e.g. if it appears there
-is more than 1 TRX partition.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-With the S25FL127S nor flash part, each writing to the configuration
-register takes hundreds of ms. During that time, no more accesses to
-the flash should be done (even reads).
-
-This commit adds a wait loop after the register writing until the flash
-finishes its work.
-
-This issue could make rootfs mounting fail when the latter was done too
-much closely to this quad enable bit setting step. And in this case, a
-driver as UBIFS may try to recover the filesystem and may broke it
-completely.

-Subject: [PATCH] mtd: spi-nor: Add support for S3AN spi-nor devices
-
-Xilinx Spartan-3AN FPGAs contain an In-System Flash where they keep
-their configuration data and (optionally) some user data.
-
-The protocol of this flash follows most of the spi-nor standard. With
-the following differences:
-
-- Page size might not be a power of two.
-- The address calculation (default addressing mode).
-- The spi nor commands used.
-
-Protocol is described on Xilinx User Guide UG333

-
-This patch removes the WARN_ONCE() test in spi_nor_write().
-This macro triggers the display of a warning message almost every time we
-use a UBI file-system because a write operation is performed at offset 64,
-which is in the middle of the SPI NOR memory page. This is a valid
-operation for ubifs.
-
-Hence this warning is pretty annoying and useless so we just remove it.

-Subject: [PATCH] mtd: spi-nor: rename SPINOR_OP_* macros of the 4-byte address
- op codes
-
-This patch renames the SPINOR_OP_* macros of the 4-byte address
-instruction set so the new names all share a common pattern: the 4-byte
-address name is built from the 3-byte address name appending the "_4B"
-suffix.
-
-The patch also introduces new op codes to support other SPI protocols such
-as SPI 1-4-4 and SPI 1-2-2.
-
-This is a transitional patch and will help a later patch of spi-nor.c
-to automate the translation from the 3-byte address op codes into their
-4-byte address version.

-Subject: [PATCH] mtd: spi-nor: add a stateless method to support memory size
- above 128Mib
-
-This patch provides an alternative mean to support memory above 16MiB
-(128Mib) by replacing 3byte address op codes by their associated 4byte
-address versions.
-
-Using the dedicated 4byte address op codes doesn't change the internal
-state of the SPI NOR memory as opposed to using other means such as
-updating a Base Address Register (BAR) and sending command to enter/leave
-the 4byte mode.
-
-Hence when a CPU reset occurs, early bootloaders don't need to be aware
-of BAR value or 4byte mode being enabled: they can still access the first
-16MiB of the SPI NOR memory using the regular 3byte address op codes.

-Subject: [PATCH] mtd: handle partitioning on devices with 0 erasesize
-
-erasesize is meaningful for flash devices but for SRAM there is no
-concept of an erase block so erasesize is set to 0. When partitioning
-these devices instead of ensuring partitions fall on erasesize
-boundaries we ensure they fall on writesize boundaries.

-When support for sysfs "offset" file was added it missed to update the

-Subject: [PATCH] mtd: partitions: rename "master" to the "parent" where
- appropriate
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This prepares mtd subsystem for the new feature: subpartitions. In some
-cases flash device partition can be a container with extra subpartitions
-(volumes).
-
-So far there was a flat structure implemented. One master (flash device)
-could be partitioned into few partitions. Every partition got its master
-and it was enough to get things running.
-
-To support subpartitions we need to store pointer to the parent for each
-partition. This is required to implement more natural tree structure and
-handle all recursion and offsets calculation.
-
-To make code consistent this patch renamed "master" to the "parent" in
-places where we can be dealing with subpartitions.

-Subject: [PATCH] mtd: partitions: add support for partition parsers
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Some devices have partitions that are kind of containers with extra
-subpartitions / volumes instead of e.g. a simple filesystem data. To
-support such cases we need to first create normal flash device
-partitions and then take care of these special ones.
-
-It's very common case for home routers. Depending on the vendor there
-are formats like TRX, Seama, TP-Link, WRGG & more. All of them are used
-to embed few partitions into a single one / single firmware file.
-
-Ideally all vendors would use some well documented / standardized format
-like UBI (and some probably start doing so), but there are still
-countless devices on the market using these poor vendor specific
-formats.
-
-This patch extends MTD subsystem by allowing to specify list of parsers
-that should be tried for a given partition. Supporting such poor formats
-is highly unlikely to be the top priority so these changes try to
-minimize maintenance cost to the minimum. It reuses existing code for
-these new parsers and just adds a one property and one new function.
-
-This implementation requires setting partition parsers in a flash
-parser. A proper change of bcm47xxpart will follow and in the future we
-will hopefully also find a solution for doing it with ofpart
-("fixed-partitions").

-Subject: [PATCH] mtd: extract TRX parser out of bcm47xxpart into a separated
- module
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This makes TRX parsing code reusable with other platforms and parsers.
-
-Please note this patch doesn't really change anything in the existing
-code, just moves it. There is still some place for improvement (e.g.
-working on non-hacky method of checking rootfs format) but it's not
-really a subject of this change.

- it
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-So far were were allocating struct bgmac in 3 places: platform code,
-bcma code and shared bgmac_enet_probe function. The reason for this was
-bgmac_enet_probe:
-1) Requiring early-filled struct bgmac
-2) Calling alloc_etherdev on its own in order to use netdev_priv later
-
-This solution got few drawbacks:
-1) Was duplicating allocating code
-2) Required copying early-filled struct
-3) Resulted in platform/bcma code having access only to unused struct
-
-Solve this situation by simply extracting some probe code into the new
-bgmac_alloc function.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Adding struct bcma_mdio was a workaround for bcma code not having access

-struct we can just use it internally in bcma code.
-
-This simplifies code & allows access to all bgmac driver details from

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit

-This adds support for using bgmac with PHYs supported by standalone PHY
-drivers. Having any PHY initialization in bgmac is hacky and shouldn't
-be extended but rather removed if anyone has hardware to test it.

-Subject: [PATCH] net: phy: broadcom: Add BCM54810 PHY entry
-
-The BCM54810 PHY requires some semi-unique configuration, which results
-in some additional configuration in addition to the standard config.
-Also, some users of the BCM54810 require the PHY lanes to be swapped.
-Since there is no way to detect this, add a device tree query to see if
-it is applicable.

-Starting with commit 5b4e29005123 ("net: phy: broadcom: add
-bcm54xx_auxctl_read") we have a reading helper so use it and avoid code
-duplication.
-It also means we don't need MII_BCM54XX_AUXCTL_SHDWSEL_MISC define as
-it's the same as MII_BCM54XX_AUXCTL_SHDWSEL_MISC just for reading needs
-(same value shifted by 12 bits).

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This extra BCM54612E code in PHY driver isn't really aneg specific. Even
-without it aneg works OK but the problem is no packets pass through PHY.
-
-Moreover putting this code inside config_aneg callback didn't allow
-resuming PHY correctly. When driver called phy_stop and phy_start it was
-putting PHY machine into RESUMING state. After that machine was
-switching into AN and NOLINK without ever calling phy_start_aneg. This
-prevented this extra setup from being called and PHY didn't work.
-
-This change has been verified to fix network on BCM47186B0 SoC device
-with BCM54612E.

-Subject: [PATCH] regmap: make LZO cache optional
-
-Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support
-for LZO compression in regcache, but there were never any users added
-afterwards. Since LZO support itself has its own size, it currently is
-rather a deoptimization.
-
-So make it optional by introducing a symbol that can be selected by
-drivers wanting to make use of it.
-
-Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).
-

----
-I tried using google to find any users (even out-of-tree ones), but at
-best I found a single driver submission that was switched to RBTREE in
-subsequent resubmissions (MFD_SMSC).
-
-One could maybe also just drop the code because of no users for 5 years,
-but that would be up to the maintainer(s) to decide.

-Subject: [PATCH] MIPS: fix cache flushing for highmem pages
-
-Most cache flush ops were no-op for highmem pages. This led to nasty
-segfaults and (in the case of page_address(page) == NULL) kernel
-crashes.
-
-Fix this by always flushing highmem pages using kmap/kunmap_atomic
-around the actual cache flush. This might be a bit inefficient, but at
-least it's stable.

-This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
-page_to_pfn anymore.
-
-The following output was generated with two hacked in printk statements:
-
-printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
-(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
- if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
- mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
-printk("after %p\n", mem_map);
-
-Output:
-
-[ 0.000000] before 8861b280 vs. 8861b280 or 8851b280
-[ 0.000000] after 8851b280
-
-As seen in the first line mem_map with subtraction of offset does not equal the
-mem_map after subtraction of ARCH_PFN_OFFSET.
-
-After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
-previously calculated offset is zero for the named platform it is able to boot
-4.4 and 4.9-rc7 again.

-Subject: MIPS: PCI: add controllers before the specified head
-
-With commit 23dac14d058f ("MIPS: PCI: Use struct list_head lists") new
-controllers are added after the specified head where they were added
-before the specified head previously.
-
-Use list_add_tail to restore the former order.
-
-This patches fixes the following PCI error on lantiq:
-
- pci 0000:01:00.0: BAR 0: error updating (0x1c000004 != 0x000000)

-Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
-
-including sysinfo.h from kernel.h makes no sense whatsoever,
-but removing it breaks glibc's userspace header,
-which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
-this seems to be a historical mistake.
-on musl, including any header that uses kernel.h directly or indirectly
-plus sys/sysinfo.h will produce a compile error due to redefinition of
-struct sysinfo from sys/sysinfo.h.
-so for now, only include it on glibc or when including from kernel
-in order not to break their headers.

-Subject: [PATCH 2/3] uapi/libc-compat.h: do not rely on __GLIBC__
-
-Musl provides the same structs as glibc, but does not provide a define to
-allow its detection. Since the absence of __GLIBC__ also can mean that it
-is included from the kernel, change the __GLIBC__ detection to
-!__KERNEL__, which should always be true when included from userspace.

-Subject: [RFC PATCH v4 2/2] MIPS: make FPU emulator optional
-Date: Mon, 7 Apr 2014 12:57:04 +0200
-Message-Id: <1396868224-252888-2-git-send-email-manuel.lauss@gmail.com>
-
-This small patch makes the MIPS FPU emulator optional. The kernel
-kills float-users on systems without a hardware FPU by sending a SIGILL.
-
-Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
-optimizing for size).
-
-Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com>
----
-v4: rediffed because of patch 1/2, should now work with micromips as well
-v3: updated patch description with size savings.
-v2: incorporated changes suggested by Jonas Gorski
- force the fpu emulator on for micromips: relocating the parts
- of the mmips code in the emulator to other areas would be a
- much larger change; I went the cheap route instead with this.

-+ help
-+ This option lets you disable the built-in MIPS FPU (Coprocessor 1)
-+ emulator, which handles floating-point instructions on processors
-+ without a hardware FPU. It is generally a good idea to keep the
-+ emulator built-in, unless you are perfectly sure you have a
-+ complete soft-float environment. With the emulator disabled, all
-+ users of float operations will be killed with an illegal instr-
-+ uction exception.

-Subject: [PATCH 2/2] openwrt: arc - add OWRTDTB section
-
-This change allows OpenWRT to patch resulting kernel binary with
-external .dtb.
-
-That allows us to re-use exactky the same vmlinux on different boards
-given its ARC core configurations match (at least cache line sizes etc).
-
-""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
-.dtb right after it, keeping the string in place.

-Subject: [PATCH] arc: enable unaligned access in kernel mode
-
-This enables misaligned access handling even in kernel mode.
-Some wireless drivers (ath9k-htc and mt7601u) use misaligned accesses
-here and there and to cope with that without fixing stuff in the drivers
-we're just gracefully handling it on ARC.

-+ MyLoader is a bootloader which allows the user to define partitions
-+ in flash devices, by putting a table in the second erase block
-+ on the device, similar to a partition table. This table gives the
-+ offsets and lengths of the user defined partitions.
-+
-+ If you need code which can detect and parse these tables, and
-+ register MTD 'partitions' corresponding to each image detected,
-+ enable this option.
-+
-+ You will still need the parsing functions to be called by the driver
-+ for your particular device. It won't happen automatically.

-Subject: [PATCH] Add support for MAP-E FMRs (mesh mode)
-
-MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
-between MAP CEs (mesh mode) without the need to forward such data to a
-border relay. This is similar to how 6rd works but for IPv4 over IPv6.

-Subject: [PATCH 1/2] ipv6: allow rejecting with "source address failed policy"
-
-RFC6204 L-14 requires rejecting traffic from invalid addresses with
-ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
-egress policy) on the LAN side, so add an appropriate rule for that.

-Subject: NET: skip GRO for foreign MAC addresses
-
-For network drivers using napi_gro_receive, packets are run through GRO,
-even when the destination MAC address does not match, and they're supposed
-to be delivered to another host behind a different bridge port.
-
-This can be very expensive, because for drivers without TSO or scatter-
-gather, this can only be undone by copying the skb and checksumming it
-again.
-
-To be able to track foreign MAC addresses in an inexpensive way, create
-a mask of changed bits in MAC addresses of upper devices. This allows
-handling VLANs and bridge devices with different addresses (as long as
-they are not too different).

-There're some discussions in mailing lists proposing to disable
-that particular check alltogether and magically all seem to work
-fine with muted warning.
-
-Anyways new thread on that regard could be found here:
-http://lists.infradead.org/pipermail/linux-snps-arc/2016-July/001310.html
-
-Let's see what comes out of that new discussion, hopefully patching
-of generic USB stuff won't be required then.

-Subject: [PATCH] libata: add ledtrig support
-To: linux-ide@vger.kernel.org,
- Tejun Heo <tj@kernel.org>
-
-This adds a LED trigger for each ATA port indicating disk activity.
-
-As this is needed only on specific platforms (NAS SoCs and such),
-these platforms should define ARCH_WANTS_LIBATA_LEDS if there
-are boards with LED(s) intended to indicate ATA disk activity and
-need the OS to take care of that.
-In that way, if not selected, LED trigger support not will be
-included in libata-core and both, codepaths and structures remain
-untouched.

+Subject: netfilter: conntrack: cache route for forwarded connections
+
+... to avoid per-packet FIB lookup if possible.
+
+The cached dst is re-used provided the input interface
+is the same as that of the previous packet in the same direction.
+
+If not, the cached dst is invalidated.
+
+For ipv6 we also need to store sernum, else dst_check doesn't work,
+pointed out by Eric Dumazet.
+
+This should speed up forwarding when conntrack is already in use
+anyway, especially when using reverse path filtering -- active RPF
+enforces two FIB lookups for each packet.
+
+Before the routing cache removal this didn't matter since RPF was performed
+only when route cache didn't yield a result; but without route cache it
+comes at higher price.
+
+Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
+avoid holding on to dsts of 'frozen' conntracks.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Network managers like netifd (used in OpenWRT for instance) try to
+configure interface options after creation but before setting the
+interface up.
+
+Unfortunately the sysfs / bridge currently only allows to configure the
+hash_max and multicast_router options when the bridge interface is up.
+But since br_multicast_init() doesn't start any timers and only sets
+default values and initializes timers it should be save to reconfigure
+the default values after that, before things actually get active after
+the bridge is set up.

+Subject: [PATCH] bgmac: leave interrupts disabled as long as there is work
+ to do
+
+Always poll rx and tx during NAPI poll instead of relying on the status
+of the first interrupt. This prevents bgmac_poll from leaving unfinished
+work around until the next IRQ.
+In my tests this makes bridging/routing throughput under heavy load more
+stable and ensures that no new IRQs arrive as long as bgmac_poll uses up

+Subject: [PATCH] bgmac: fix DMA rx corruption
+
+The driver needs to inform the hardware about the first invalid (not yet
+filled) rx slot, by writing its DMA descriptor pointer offset to the
+BGMAC_DMA_RX_INDEX register.
+
+This register was set to a value exceeding the rx ring size, effectively
+allowing the hardware constant access to the full ring, regardless of
+which slots are initialized.
+
+To fix this issue, always mark the last filled rx slot as invalid.

+Subject: [PATCH] fib_trie: Fix /proc/net/fib_trie when
+ CONFIG_IP_MULTIPLE_TABLES is not defined
+
+In recent testing I had disabled CONFIG_IP_MULTIPLE_TABLES and as a result
+when I ran "cat /proc/net/fib_trie" the main trie was displayed multiple
+times. I found that the problem line of code was in the function
+fib_trie_seq_next. Specifically the line below caused the indexes to go in
+the opposite direction of our traversal:
+
+ h = tb->tb_id & (FIB_TABLE_HASHSZ - 1);
+
+This issue was that the RT tables are defined such that RT_TABLE_LOCAL is ID
+255, while it is located at TABLE_LOCAL_INDEX of 0, and RT_TABLE_MAIN is 254
+with a TABLE_MAIN_INDEX of 1. This means that the above line will return 1
+for the local table and 0 for main. The result is that fib_trie_seq_next
+will return NULL at the end of the local table, fib_trie_seq_start will
+return the start of the main table, and then fib_trie_seq_next will loop on
+main forever as h will always return 0.
+
+The fix for this is to reverse the ordering of the two tables. It has the
+advantage of making it so that the tables now print in the same order
+regardless of if multiple tables are enabled or not. In order to make the
+definition consistent with the multiple tables case I simply masked the to
+RT_TABLE_XXX values by (FIB_TABLE_HASHSZ - 1). This way the two table
+layouts should always stay consistent.

+Subject: [PATCH] fib_trie: Fix trie balancing issue if new node pushes down
+ existing node
+
+This patch addresses an issue with the level compression of the fib_trie.
+Specifically in the case of adding a new leaf that triggers a new node to
+be added that takes the place of the old node. The result is a trie where
+the 1 child tnode is on one side and one leaf is on the other which gives
+you a very deep trie. Below is the script I used to generate a trie on
+dummy0 with a 10.X.X.X family of addresses.
+
+ ip link add type dummy
+ ipval=184549374
+ bit=2
+ for i in `seq 1 23`
+ do
+ ifconfig dummy0:$bit $ipval/8
+ ipval=`expr $ipval - $bit`
+ bit=`expr $bit \* 2`
+ done
+ cat /proc/net/fib_triestat
+
+Running the script before the patch:
+
+ Local:
+ Aver depth: 10.82
+ Max depth: 23
+ Leaves: 29
+ Prefixes: 30
+ Internal nodes: 27
+ 1: 26 2: 1
+ Pointers: 56
+ Null ptrs: 1
+ Total size: 5 kB
+
+After applying the patch and repeating:
+
+ Local:
+ Aver depth: 4.72
+ Max depth: 9
+ Leaves: 29
+ Prefixes: 30
+ Internal nodes: 12
+ 1: 3 2: 2 3: 7
+ Pointers: 70
+ Null ptrs: 30
+ Total size: 4 kB
+
+What this fix does is start the rebalance at the newly created tnode
+instead of at the parent tnode. This way if there is a gap between the
+parent and the new node it doesn't prevent the new tnode from being
+coalesced with any pre-existing nodes that may have been pushed into one
+of the new nodes child branches.

+Subject: [PATCH] fib_trie: Update usage stats to be percpu instead of
+ global variables
+
+The trie usage stats were currently being shared by all threads that were
+calling fib_table_lookup. As a result when multiple threads were
+performing lookups simultaneously the trie would begin to cache bounce
+between those threads.
+
+In order to prevent this I have updated the usage stats to use a set of
+percpu variables. By doing this we should be able to avoid the cache
+bouncing and still make use of these stats.

+Subject: [PATCH] fib_trie: Make leaf and tnode more uniform
+
+This change makes some fundamental changes to the way leaves and tnodes are
+constructed. The big differences are:
+1. Leaves now populate pos and bits indicating their full key size.
+2. Trie nodes now mask out their lower bits to be consistent with the leaf
+3. Both structures have been reordered so that rt_trie_node now consisists
+ of a much larger region including the pos, bits, and rcu portions of
+ the tnode structure.
+
+On 32b systems this will result in the leaf being 4B larger as the pos and
+bits values were added to a hole created by the key as it was only 4B in
+length.

+Subject: [PATCH] fib_trie: Merge tnode_free and leaf_free into node_free
+
+Both the leaf and the tnode had an rcu_head in them, but they had them in
+slightly different places. Since we now have them in the same spot and
+know that any node with bits == 0 is a leaf and the rest are either vmalloc
+or kmalloc tnodes depending on the value of bits it makes it easy to combine
+the functions and reduce overhead.
+
+In addition I have taken advantage of the rcu_head pointer to go ahead and
+put together a simple linked list instead of using the tnode pointer as
+this way we can merge either type of structure for freeing.

+Subject: [PATCH] fib_trie: Merge leaf into tnode
+
+This change makes it so that leaf and tnode are the same struct. As a
+result there is no need for rt_trie_node anymore since everyting can be
+merged into tnode.
+
+On 32b systems this results in the leaf being 4 bytes larger, however I
+don't know if that is really an issue as this and an eariler patch that
+added bits & pos have increased the size from 20 to 28. If I am not
+mistaken slub/slab allocate on power of 2 sizes so 20 was likely being
+rounded up to 32 anyway.

+Subject: [PATCH] fib_trie: Optimize fib_table_lookup to avoid wasting
+ time on loops/variables
+
+This patch is meant to reduce the complexity of fib_table_lookup by reducing
+the number of variables to the bare minimum while still keeping the same if
+not improved functionality versus the original.
+
+Most of this change was started off by the desire to rid the function of
+chopped_off and current_prefix_length as they actually added very little to
+the function since they only applied when computing the cindex. I was able
+to replace them mostly with just a check for the prefix match. As long as
+the prefix between the key and the node being tested was the same we know
+we can search the tnode fully versus just testing cindex 0.
+
+The second portion of the change ended up being a massive reordering.
+Originally the calls to check_leaf were up near the start of the loop, and
+the backtracing and descending into lower levels of tnodes was later. This
+didn't make much sense as the structure of the tree means the leaves are
+always the last thing to be tested. As such I reordered things so that we
+instead have a loop that will delve into the tree and only exit when we
+have either found a leaf or we have exhausted the tree. The advantage of
+rearranging things like this is that we can fully inline check_leaf since
+there is now only one reference to it in the function.

+Subject: [PATCH] fib_trie: Update meaning of pos to represent unchecked
+ bits
+
+This change moves the pos value to the other side of the "bits" field. By
+doing this it actually simplifies a significant amount of code in the trie.
+
+For example when halving a tree we know that the bit lost exists at
+oldnode->pos, and if we inflate the tree the new bit being add is at
+tn->pos. Previously to find those bits you would have to subtract pos and
+bits from the keylength or start with a value of (1 << 31) and then shift
+that.
+
+There are a number of spots throughout the code that benefit from this. In
+the case of the hot-path searches the main advantage is that we can drop 2
+or more operations from the search path as we no longer need to compute the
+value for the index to be shifted by and can instead just use the raw pos
+value.
+
+In addition the tkey_extract_bits is now defunct and can be replaced by
+get_index since the two operations were doing the same thing, but now
+get_index does it much more quickly as it is only an xor and shift versus a
+pair of shifts and a subtraction.

+Subject: [PATCH] fib_trie: Use unsigned long for anything dealing with a
+ shift by bits
+
+This change makes it so that anything that can be shifted by, or compared
+to a value shifted by bits is updated to be an unsigned long. This is
+mostly a precaution against an insanely huge address space that somehow
+starts coming close to the 2^32 root node size which would require
+something like 1.5 billion addresses.
+
+I chose unsigned long instead of unsigned long long since I do not believe
+it is possible to allocate a 32 bit tnode on a 32 bit system as the memory
+consumed would be 16GB + 28B which exceeds the addressible space for any
+one process.

+Subject: [PATCH] fib_trie: Push rcu_read_lock/unlock to callers
+
+This change is to start cleaning up some of the rcu_read_lock/unlock
+handling. I realized while reviewing the code there are several spots that
+I don't believe are being handled correctly or are masking warnings by
+locally calling rcu_read_lock/unlock instead of calling them at the correct
+level.
+
+A common example is a call to fib_get_table followed by fib_table_lookup.
+The rcu_read_lock/unlock ought to wrap both but there are several spots where
+they were not wrapped.

+- * From "Implementing a dynamic compressed trie" by Stefan Nilsson of
+- * the Helsinki University of Technology and Matti Tikkanen of Nokia
+- * Telecommunications, page 6:
+- * "A node is doubled if the ratio of non-empty children to all
+- * children in the *doubled* node is at least 'high'."
+- *
+- * 'high' in this instance is the variable 'inflate_threshold'. It
+- * is expressed as a percentage, so we multiply it with
+- * tnode_child_length() and instead of multiplying by 2 (since the
+- * child array will be doubled by inflate()) and multiplying
+- * the left-hand side by 100 (to handle the percentage thing) we
+- * multiply the left-hand side by 50.
+- *
+- * The left-hand side may look a bit weird: tnode_child_length(tn)
+- * - tn->empty_children is of course the number of non-null children
+- * in the current node. tn->full_children is the number of "full"
+- * children, that is non-null tnodes with a skip value of 0.
+- * All of those will be doubled in the resulting inflated tnode, so
+- * we just count them one extra time here.
+- *
+- * A clearer way to write this would be:
+- *
+- * to_be_doubled = tn->full_children;
+- * not_to_be_doubled = tnode_child_length(tn) - tn->empty_children -
+- * tn->full_children;
+- *
+- * new_child_length = tnode_child_length(tn) * 2;
+- *
+- * new_fill_factor = 100 * (not_to_be_doubled + 2*to_be_doubled) /
+- * new_child_length;
+- * if (new_fill_factor >= inflate_threshold)
+- *
+- * ...and so on, tho it would mess up the while () loop.
+- *
+- * anyway,
+- * 100 * (not_to_be_doubled + 2*to_be_doubled) / new_child_length >=
+- * inflate_threshold
+- *
+- * avoid a division:
+- * 100 * (not_to_be_doubled + 2*to_be_doubled) >=
+- * inflate_threshold * new_child_length
+- *
+- * expand not_to_be_doubled and to_be_doubled, and shorten:
+- * 100 * (tnode_child_length(tn) - tn->empty_children +
+- * tn->full_children) >= inflate_threshold * new_child_length
+- *
+- * expand new_child_length:
+- * 100 * (tnode_child_length(tn) - tn->empty_children +
+- * tn->full_children) >=
+- * inflate_threshold * tnode_child_length(tn) * 2
+- *
+- * shorten again:

+Subject: [PATCH] fib_trie: Add functions should_inflate and should_halve
+
+This change pulls the logic for if we should inflate/halve the nodes out
+into separate functions. It also addresses what I believe is a bug where 1
+full node is all that is needed to keep a node from ever being halved.
+
+Simple script to reproduce the issue:
+ modprobe dummy; ifconfig dummy0 up
+ for i in `seq 0 255`; do ifconfig dummy0:$i 10.0.${i}.1/24 up; done
+ ifconfig dummy0:256 10.0.255.33/16 up
+ for i in `seq 0 254`; do ifconfig dummy0:$i down; done
+
+Results from /proc/net/fib_triestat

+Subject: [PATCH] fib_trie: Push tnode flushing down to inflate/halve
+
+This change pushes the tnode freeing down into the inflate and halve
+functions. It makes more sense here as we have a better grasp of what is
+going on and when a given cluster of nodes is ready to be freed.
+
+I believe this may address a bug in the freeing logic as well. For some
+reason if the freelist got to a certain size we would call
+synchronize_rcu(). I'm assuming that what they meant to do is call
+synchronize_rcu() after they had handed off that much memory via
+call_rcu(). As such that is what I have updated the behavior to be.

+ way
+
+This change pulls the node_set_parent functionality out of put_child_reorg
+and instead leaves that to the function to take care of as well. By doing
+this we can fully construct the new cluster of tnodes and all of the
+pointers out of it before we start routing pointers into it.
+
+I am suspecting this will likely fix some concurency issues though I don't
+have a good test to show as such.

+Subject: [PATCH] fib_trie: Remove checks for index >= tnode_child_length
+ from tnode_get_child
+
+For some reason the compiler doesn't seem to understand that when we are in
+a loop that runs from tnode_child_length - 1 to 0 we don't expect the value
+of tn->bits to change. As such every call to tnode_get_child was rerunning
+tnode_chile_length which ended up consuming quite a bit of space in the
+resultant assembly code.
+
+I have gone though and verified that in all cases where tnode_get_child
+is used we are either winding though a fixed loop from tnode_child_length -
+1 to 0, or are in a fastpath case where we are verifying the value by
+either checking for any remaining bits after shifting index by bits and
+testing for leaf, or by using tnode_child_length.

+Subject: [PATCH] fib_trie: Add tracking value for suffix length
+
+This change adds a tracking value for the maximum suffix length of all
+prefixes stored in any given tnode. With this value we can determine if we
+need to backtrace or not based on if the suffix is greater than the pos
+value.
+
+By doing this we can reduce the CPU overhead for lookups in the local table
+as many of the prefixes there are 32b long and have a suffix length of 0
+meaning we can immediately backtrace to the root node without needing to
+test any of the nodes between it and where we ended up.

+Subject: [PATCH] fib_trie: Fix RCU bug and merge similar bits of inflate/halve
+
+This patch addresses two issues.
+
+The first issue is the fact that I believe I had the RCU freeing sequence
+slightly out of order. As a result we could get into an issue if a caller
+went into a child of a child of the new node, then backtraced into the to be
+freed parent, and then attempted to access a child of a child that may have
+been consumed in a resize of one of the new nodes children. To resolve this I
+have moved the resize after we have freed the oldtnode. The only side effect
+of this is that we will now be calling resize on more nodes in the case of
+inflate due to the fact that we don't have a good way to test to see if a
+full_tnode on the new node was there before or after the allocation. This
+should have minimal impact however since the node should already be
+correctly size so it is just the cost of calling should_inflate that we
+will be taking on the node which is only a couple of cycles.
+
+The second issue is the fact that inflate and halve were essentially doing
+the same thing after the new node was added to the trie replacing the old
+one. As such it wasn't really necessary to keep the code in both functions
+so I have split it out into two other functions, called replace and
+update_children.

+Subject: [PATCH] fib_trie: Add collapse() and should_collapse() to resize
+
+This patch really does two things.
+
+First it pulls the logic for determining if we should collapse one node out
+of the tree and the actual code doing the collapse into a separate pair of
+functions. This helps to make the changes to these areas more readable.
+
+Second it encodes the upper 32b of the empty_children value onto the
+full_children value in the case of bits == KEYLENGTH. By doing this we are
+able to handle the case of a 32b node where empty_children would appear to
+be 0 when it was actually 1ul << 32.

+Subject: [PATCH] fib_trie: Various clean-ups for handling slen
+
+While doing further work on the fib_trie I noted a few items.
+
+First I was using calls that were far more complicated than they needed to
+be for determining when to push/pull the suffix length. I have updated the
+code to reflect the simplier logic.
+
+The second issue is that I realised we weren't necessarily handling the
+case of a leaf_info struct surviving a flush. I have updated the logic so
+that now we will call pull_suffix in the event of having a leaf info value
+left in the leaf after flushing it.

+Subject: [PATCH] pppoe: Use workqueue to die properly when a PADT is received
+
+When a PADT frame is received, the socket may not be in a good state to
+close down the PPP interface. The current implementation handles this by
+simply blocking all further PPP traffic, and hoping that the lack of traffic
+will trigger the user to investigate.
+
+Use schedule_work to get to a process context from which we clear down the
+PPP interface, in a fashion analogous to hangup on a TTY-based PPP
+interface. This causes pppd to disconnect immediately, and allows tools to
+take immediate corrective action.
+
+Note that pppd's rp_pppoe.so plugin has code in it to disable the session
+when it disconnects; however, as a consequence of this patch, the session is
+already disabled before rp_pppoe.so is asked to disable the session. The
+result is a harmless error message:
+
+Failed to disconnect PPPoE socket: 114 Operation already in progress
+
+This message is safe to ignore, as long as the error is 114 Operation
+already in progress; in that specific case, it means that the PPPoE session
+has already been disabled before pppd tried to disable it.

+Subject: [PATCH] ipv6: ip6_fragment: fix headroom tests and skb leak
+
+David Woodhouse reports skb_under_panic when we try to push ethernet
+header to fragmented ipv6 skbs:
+
+ skbuff: skb_under_panic: text:c1277f1e len:1294 put:14 head:dec98000
+ data:dec97ffc tail:0xdec9850a end:0xdec98f40 dev:br-lan
+[..]
+ip6_finish_output2+0x196/0x4da
+
+David further debugged this:
+ [..] offending fragments were arriving here with skb_headroom(skb)==10.
+ Which is reasonable, being the Solos ADSL card's header of 8 bytes
+ followed by 2 bytes of PPP frame type.
+
+The problem is that if netfilter ipv6 defragmentation is used, skb_cow()
+in ip6_forward will only see reassembled skb.
+
+Therefore, headroom is overestimated by 8 bytes (we pulled fragment
+header) and we don't check the skbs in the frag_list either.
+
+We can't do these checks in netfilter defrag since outdev isn't known yet.
+
+Furthermore, existing tests in ip6_fragment did not consider the fragment
+or ipv6 header size when checking headroom of the fraglist skbs.
+
+While at it, also fix a skb leak on memory allocation -- ip6_fragment
+must consume the skb.
+
+I tested this e1000 driver hacked to not allocate additional headroom
+(we end up in slowpath, since LL_RESERVED_SPACE is 16).
+
+If 2 bytes of headroom are allocated, fastpath is taken (14 byte
+ethernet header was pulled, so 16 byte headroom available in all
+fragments).

+Subject: [PATCH] solos-pci: Increase headroom on received packets
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+A comment in include/linux/skbuff.h says that:
+
+ * Various parts of the networking layer expect at least 32 bytes of
+ * headroom, you should not reduce this.
+
+This was demonstrated by a panic when handling fragmented IPv6 packets:
+http://marc.info/?l=linux-netdev&m=144236093519172&w=2
+
+It's not entirely clear if that comment is still valid — and if it is,
+perhaps netif_rx() ought to be enforcing it with a warning.
+
+But either way, it is rather stupid from a performance point of view
+for us to be receiving packets into a buffer which doesn't have enough
+room to prepend an Ethernet header — it means that *every* incoming
+packet is going to be need to be reallocated. So let's fix that.

+Subject: [PATCH] regmap: make LZO cache optional
+
+Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support
+for LZO compression in regcache, but there were never any users added
+afterwards. Since LZO support itself has its own size, it currently is
+rather a deoptimization.
+
+So make it optional by introducing a symbol that can be selected by
+drivers wanting to make use of it.
+
+Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).

+I tried using google to find any users (even out-of-tree ones), but at
+best I found a single driver submission that was switched to RBTREE in
+subsequent resubmissions (MFD_SMSC).
+
+One could maybe also just drop the code because of no users for 5 years,
+but that would be up to the maintainer(s) to decide.

+
+The work directory is needed for atomic copy-up and similar. It is not actually
+necessary to mount a read-only overlay. Post 4.0 it is possible to mount the
+overlay without workdir (but even then it won't happen automatically in case the
+upper fs is full, so this should be fixed in the latest kernel too).
+
+Could you please try the following patch? If the workdir can't be created it
+will fall back to mounting the overlay read-only.
+
+Thanks,
+Miklos

+Subject: [PATCH] spi: Pump transfers inside calling context for spi_sync()
+
+If we are using the standard SPI message pump (which all drivers should be
+transitioning over to) then special case the message enqueue and instead of
+starting the worker thread to push messages to the hardware do so in the
+context of the caller if the controller is idle. This avoids a context
+switch in the common case where the controller has a single user in a
+single thread, for short PIO transfers there may be no need to context
+switch away from the calling context to complete the transfer.
+
+The code is a bit more complex than is desirable in part due to the need
+to handle drivers not using the standard queue and in part due to handling
+the various combinations of bus locking and asynchronous submission in
+interrupt context.
+
+It is still suboptimal since it will still wake the message pump for each
+transfer in order to schedule idling of the hardware and if multiple
+contexts are using the controller simultaneously a caller may end up
+pumping a message for some random other thread rather than for itself,
+and if the thread ends up deferring due to another context idling the
+hardware then it will just busy wait. It can, however, have the benefit
+of aggregating power up and down of the hardware when a caller performs
+a series of transfers back to back without any need for the use of
+spi_async().

+
+[ Upstream commit 19be0eaffa3ac7d8eb6784ad9bdbc7d67ed8e619 ]
+
+This is an ancient bug that was actually attempted to be fixed once
+(badly) by me eleven years ago in commit 4ceb5db9757a ("Fix
+get_user_pages() race for write access") but that was then undone due to
+problems on s390 by commit f33ea7f404e5 ("fix get_user_pages bug").
+
+In the meantime, the s390 situation has long been fixed, and we can now
+fix it by checking the pte_dirty() bit properly (and do it better). The
+s390 dirty bit was implemented in abf09bed3cce ("s390/mm: implement
+software dirty bits") which made it into v3.9. Earlier kernels will
+have to look at the page state itself.
+
+Also, the VM has become more scalable, and what used a purely
+theoretical race back then has become easier to trigger.
+
+To fix it, we introduce a new internal FOLL_COW flag to mark the "yes,
+we already did a COW" rather than play racy games with FOLL_WRITE that
+is very fundamental, and then use the pte dirty flag to validate that
+the FOLL_COW flag is still valid.

+
+Archs have been abusing module_free() to clean up their arch-specific
+allocations. Since module_free() is also (ab)used by BPF and trace code,
+let's keep it to simple allocations, and provide a hook called before
+that.
+
+This means that avr32, ia64, parisc and s390 no longer need to implement
+their own module_free() at all. avr32 doesn't need module_finalize()

+ checking
+
+This patch adds an ignore_oc flag which can be set by EHCI controller
+not supporting or wanting to disable overcurrent checking. The EHCI
+platform data in include/linux/usb/ehci_pdriver.h is also augmented to
+take advantage of this new flag.

+Subject: bridge: allow receiption on disabled port
+
+When an ethernet device is enslaved to a bridge, and the bridge STP
+detects loss of carrier (or operational state down), then normally
+packet receiption is blocked.
+
+This breaks control applications like WPA which maybe expecting to
+receive packets to negotiate to bring link up. The bridge needs to
+block forwarding packets from these disabled ports, but there is no
+hard requirement to not allow local packet delivery.

+
+Several DMA ops are no-op on many platforms, and the indirection through
+the mips_dma_map_ops function table is causing the compiler to emit
+unnecessary code.
+
+Inlining visibly improves network performance in my tests (on a 24Kc

+Subject: [PATCH] MIPS: UAPI: Ignore __arch_swab{16,32,64} when using MIPS16
+
+Some GCC versions (e.g. 4.8.3) can incorrectly inline a function with
+MIPS32 instructions into another function with MIPS16 code [1], causing
+the assembler to genereate incorrect binary code or fail right away
+complaining about unrecognized opcode.
+
+In the case of __arch_swab{16,32}, when inlined by the compiler with
+flags `-mips32r2 -mips16 -Os', the assembler can fail with the following
+error.
+
+ {standard input}:79: Error: unrecognized opcode `wsbh $2,$2'
+
+For performance concerns and to workaround the issue already existing in
+older compilers, just ignore these 2 functions when compiling with
+mips16 enabled.
+
+ [1] Inlining nomips16 function into mips16 function can result in
+ undefined builtins, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55777

+
+This moves the linux,part-probe device tree parsing code from

+providing a reference to their device tree node in struct
+mtd_part_parser_data.

+
+BCM5301X devices may contain some partitions in higher memory, e.g.
+Netgear R8000 has board_data at 0x2600000. To detect them we should
+use size limit on MIPS only.

+Subject: [PATCH] cdc_ncm: Add support for moving NDP to end of NCM frame
+
+NCM specs are not actually mandating a specific position in the frame for
+the NDP (Network Datagram Pointer). However, some Huawei devices will
+ignore our aggregates if it is not placed after the datagrams it points
+to. Add support for doing just this, in a per-device configurable way.
+While at it, update NCM subdrivers, disabling this functionality in all of
+them, except in huawei_cdc_ncm where it is enabled instead.
+We aren't making any distinction between different Huawei NCM devices,
+based on what the vendor driver does. Standard NCM devices are left
+unaffected: if they are compliant, they should be always usable, still
+stay on the safe side.
+
+This change has been tested and working with a Huawei E3131 device (which
+works regardless of NDP position), a Huawei E3531 (also working both
+ways) and an E3372 (which mandates NDP to be after indexed datagrams).
+
+V1->V2:
+- corrected wrong NDP acronym definition
+- fixed possible NULL pointer dereference
+- patch cleanup
+V2->V3:
+- Properly account for the NDP size when writing new packets to SKB

+Commit d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")
+added support for optional phys, but devm_phy_optional_get returns
+-ENOSYS if GENERIC_PHY is not enabled.
+
+This causes probe failures, even when there are no phys specified:
+
+[ 1.443365] orion-ehci f1058000.usb: init f1058000.usb fail, -38
+[ 1.449403] orion-ehci: probe of f1058000.usb failed with error -38
+
+Similar to dwc3, treat -ENOSYS as no phy.

+Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
+
+including sysinfo.h from kernel.h makes no sense whatsoever,
+but removing it breaks glibc's userspace header,
+which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
+this seems to be a historical mistake.
+on musl, including any header that uses kernel.h directly or indirectly
+plus sys/sysinfo.h will produce a compile error due to redefinition of
+struct sysinfo from sys/sysinfo.h.
+so for now, only include it on glibc or when including from kernel
+in order not to break their headers.

+Subject: [PATCH 2/3] uapi/libc-compat.h: do not rely on __GLIBC__
+
+Musl provides the same structs as glibc, but does not provide a define to
+allow its detection. Since the absence of __GLIBC__ also can mean that it
+is included from the kernel, change the __GLIBC__ detection to
+!__KERNEL__, which should always be true when included from userspace.

+Message-Id: <1396868224-252888-2-git-send-email-manuel.lauss@gmail.com>
+
+This small patch makes the MIPS FPU emulator optional. The kernel
+kills float-users on systems without a hardware FPU by sending a SIGILL.
+
+Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
+optimizing for size).

+v4: rediffed because of patch 1/2, should now work with micromips as well
+v3: updated patch description with size savings.
+v2: incorporated changes suggested by Jonas Gorski
+ force the fpu emulator on for micromips: relocating the parts
+ of the mmips code in the emulator to other areas would be a
+ much larger change; I went the cheap route instead with this.

++ MyLoader is a bootloader which allows the user to define partitions
++ in flash devices, by putting a table in the second erase block
++ on the device, similar to a partition table. This table gives the
++ offsets and lengths of the user defined partitions.
++
++ If you need code which can detect and parse these tables, and
++ register MTD 'partitions' corresponding to each image detected,
++ enable this option.
++
++ You will still need the parsing functions to be called by the driver
++ for your particular device. It won't happen automatically.

+Subject: [PATCH 3/7] skb_reduce_truesize: helper function for shrinking skbs
+ whenever needed
+
+On embedded devices in particular, large queues of small packets from the rx
+path with a large truesize can exist. Reducing their size can reduce
+memory pressure. skb_reduce_truesize is a helper function for doing this,

+Subject: [PATCH] Add support for MAP-E FMRs (mesh mode)
+
+MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
+between MAP CEs (mesh mode) without the need to forward such data to a
+border relay. This is similar to how 6rd works but for IPv4 over IPv6.

+Subject: [PATCH] ipv6: Fixed source specific default route handling.
+
+If there are only IPv6 source specific default routes present, the
+host gets -ENETUNREACH on e.g. connect() because ip6_dst_lookup_tail
+calls ip6_route_output first, and given source address any, it fails,
+and ip6_route_get_saddr is never called.
+
+The change is to use the ip6_route_get_saddr, even if the initial
+ip6_route_output fails, and then doing ip6_route_output _again_ after
+we have appropriate source address available.
+
+Note that this is '99% fix' to the problem; a correct fix would be to
+do route lookups only within addrconf.c when picking a source address,
+and never call ip6_route_output before source address has been
+populated.

+Subject: NET: skip GRO for foreign MAC addresses
+
+For network drivers using napi_gro_receive, packets are run through GRO,
+even when the destination MAC address does not match, and they're supposed
+to be delivered to another host behind a different bridge port.
+
+This can be very expensive, because for drivers without TSO or scatter-
+gather, this can only be undone by copying the skb and checksumming it
+again.
+
+To be able to track foreign MAC addresses in an inexpensive way, create
+a mask of changed bits in MAC addresses of upper devices. This allows
+handling VLANs and bridge devices with different addresses (as long as
+they are not too different).

+Subject: NET: add of_get_mac_address_mtd()
+
+Many embedded devices have information such as mac addresses stored inside mtd
+devices. This patch allows us to add a property inside a node describing a
+network interface. The new property points at a mtd partition with an offset
+where the mac address can be found.

+
+ 8139cp: Fix DMA unmapping of transmitted buffers
+
+ The low 16 bits of the 'opts1' field in the TX descriptor are supposed
+ to still contain the buffer length when the descriptor is handed back to
+ us. In practice, at least on my hardware, they don't. So stash the
+ original value of the opts1 field and get the length to unmap from
+ there.
+
+ There are other ways we could have worked out the length, but I actually
+ want a stash of the opts1 field anyway so that I can dump it alongside
+ the contents of the descriptor ring when we suffer a TX timeout.

+
+ 8139cp: Do not re-enable RX interrupts in cp_tx_timeout()
+
+ If an RX interrupt was already received but NAPI has not yet run when
+ the RX timeout happens, we end up in cp_tx_timeout() with RX interrupts
+ already disabled. Blindly re-enabling them will cause an IRQ storm.
+
+ (This is made particularly horrid by the fact that cp_interrupt() always
+ returns that it's handled the interrupt, even when it hasn't actually
+ done anything. If it didn't do that, the core IRQ code would have
+ detected the storm and handled it, I'd have had a clear smoking gun
+ backtrace instead of just a spontaneously resetting router, and I'd have
+ at *least* two days of my life back. Changing the return value of
+ cp_interrupt() will be argued about under separate cover.)
+
+ Unconditionally leave RX interrupts disabled after the reset, and
+ schedule NAPI to check the receive ring and re-enable them.

+Subject: [PATCH] libata: add ledtrig support
+To: linux-ide@vger.kernel.org,
+ Tejun Heo <tj@kernel.org>
+
+This adds a LED trigger for each ATA port indicating disk activity.
+
+As this is needed only on specific platforms (NAS SoCs and such),
+these platforms should define ARCH_WANTS_LIBATA_LEDS if there
+are boards with LED(s) intended to indicate ATA disk activity and
+need the OS to take care of that.
+In that way, if not selected, LED trigger support not will be
+included in libata-core and both, codepaths and structures remain
+untouched.

+Subject: [PATCH] smsc75xx: use skb_cow_head() to deal with cloned skbs
+
+We need to ensure there is enough headroom to push extra header,
+but we also need to check if we are allowed to change headers.
+
+skb_cow_head() is the proper helper to deal with this.

+Subject: [PATCH] fq_codel: add batch ability to fq_codel_drop()
+
+In presence of inelastic flows and stress, we can call
+fq_codel_drop() for every packet entering fq_codel qdisc.
+
+fq_codel_drop() is quite expensive, as it does a linear scan
+of 4 KB of memory to find a fat flow.
+Once found, it drops the oldest packet of this flow.
+
+Instead of dropping a single packet, try to drop 50% of the backlog
+of this fat flow, with a configurable limit of 64 packets per round.
+
+TCA_FQ_CODEL_DROP_BATCH_SIZE is the new attribute to make this
+limit configurable.
+
+With this strategy the 4 KB search is amortized to a single cache line
+per drop [1], so fq_codel_drop() no longer appears at the top of kernel
+profile in presence of few inelastic flows.
+
+[1] Assuming a 64byte cache line, and 1024 buckets

+Subject: [PATCH] fq_codel: add memory limitation per queue
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On small embedded routers, one wants to control maximal amount of
+memory used by fq_codel, instead of controlling number of packets or
+bytes, since GRO/TSO make these not practical.
+
+Assuming skb->truesize is accurate, we have to keep track of
+skb->truesize sum for skbs in queue.
+
+This patch adds a new TCA_FQ_CODEL_MEMORY_LIMIT attribute.
+
+I chose a default value of 32 MBytes, which looks reasonable even
+for heavy duty usages. (Prior fq_codel users should not be hurt
+when they upgrade their kernels)
+
+Two fields are added to tc_fq_codel_qd_stats to report :
+ - Current memory usage
+ - Number of drops caused by memory limits
+
+# tc qd replace dev eth1 root est 1sec 4sec fq_codel memory_limit 4M
+..
+# tc -s -d qd sh dev eth1
+qdisc fq_codel 8008: root refcnt 257 limit 10240p flows 1024

+
+My prior attempt to fix the backlogs of parents failed.
+
+If we return NET_XMIT_CN, our parents wont increase their backlog,
+so our qdisc_tree_reduce_backlog() should take this into account.
+
+v2: Florian Westphal pointed out that we could drop the packet,
+so we need to save qdisc_pkt_len(skb) in a temp variable before
+calling fq_codel_drop()

+Subject: [PATCH] mtd: bcm47xxsflash: use ioremap_cache() instead of
+ KSEG0ADDR()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Using KSEG0ADDR makes code highly MIPS dependent and not portable.
+Thanks to the fix a68f376 ("MIPS: io.h: Define `ioremap_cache'") we can
+use ioremap_cache which is generic and supported on MIPS as well now.
+
+KSEG0ADDR was translating 0x1c000000 into 0x9c000000. With ioremap_cache
+we use MIPS's __ioremap (and then remap_area_pages). This results in
+different address (e.g. 0xc0080000) but it still should be cached as
+expected and it was successfully tested with BCM47186B0.
+
+Other than that drivers/bcma/driver_chipcommon_sflash.c nicely setups a
+struct resource for access window, but we wren't using it. Use it now
+and drop duplicated info.

+Subject: [PATCH] mtd: add arch dependency for MTD_BCM47XXSFLASH symbol
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We dropped strict MIPS dependency for bcm47xxsflash driver in:
+commit 5651d6aaf489 ("mtd: bcm47xxsflash: use ioremap_cache() instead of
+KSEG0ADDR()") but using ioremap_cache still limits building it to few
+selected architectures only.
+
+A recent commit 57d8f7dd2132 ("bcma: allow enabling serial flash support
+on non-MIPS SoCs") automatically dropped MIPS dependency for
+MTD_BCM47XXSFLASH which broke building e.g. on powerpc and cris.
+
+The bcma change is alright as it doesn't break building bcma code in any
+way. MTD_BCM47XXSFLASH on the other hand should be limited to archs
+which need it and can build it (by providing ioremap_cache).

+Subject: [PATCH] mtd: bcm47xxpart: move TRX parsing code to separated function
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This change simplifies main parsing loop logic a bit. In future it may
+be useful for moving TRX support to separated module / parser (if we
+implement support for them at some point).
+Finally parsing TRX at the end puts us in a better position as we have
+better flash layout knowledge. It may be useful e.g. if it appears there
+is more than 1 TRX partition.

+enforces two FIB lookups for each packet.
+
+Before the routing cache removal this didn't matter since RPF was performed
+only when route cache didn't yield a result; but without route cache it
+comes at higher price.
+
+Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
+avoid holding on to dsts of 'frozen' conntracks.

+Subject: [PATCH] ovl: rename is_merge to is_lowest
+
+The 'is_merge' is an historical naming from when only a single lower layer
+could exist. With the introduction of multiple lower layers the meaning of
+this flag was changed to mean only the "lowest layer" (while all lower
+layers were being merged).
+
+So now 'is_merge' is inaccurate and hence renaming to 'is_lowest'

+Subject: [PATCH] ovl: override creds with the ones from the superblock mounter
+
+In user namespace the whiteout creation fails with -EPERM because the
+current process isn't capable(CAP_SYS_ADMIN) when setting xattr.
+
+A simple reproducer:
+
+$ mkdir upper lower work merged lower/dir
+$ sudo mount -t overlay overlay -olowerdir=lower,upperdir=upper,workdir=work merged
+$ unshare -m -p -f -U -r bash
+
+Now as root in the user namespace:
+
+\# touch merged/dir/{1,2,3} # this will force a copy up of lower/dir
+\# rm -fR merged/*
+
+This ends up failing with -EPERM after the files in dir has been
+correctly deleted:
+
+unlinkat(4, "2", 0) = 0
+unlinkat(4, "1", 0) = 0
+unlinkat(4, "3", 0) = 0
+close(4) = 0
+unlinkat(AT_FDCWD, "merged/dir", AT_REMOVEDIR) = -1 EPERM (Operation not
+permitted)
+
+Interestingly, if you don't place files in merged/dir you can remove it,
+meaning if upper/dir does not exist, creating the char device file works
+properly in that same location.
+
+This patch uses ovl_sb_creator_cred() to get the cred struct from the
+superblock mounter and override the old cred with these new ones so that
+the whiteout creation is possible because overlay is wrong in assuming that
+the creds it will get with prepare_creds will be in the initial user
+namespace. The old cap_raise game is removed in favor of just overriding
+the old cred struct.
+
+This patch also drops from ovl_copy_up_one() the following two lines:
+
+override_cred->fsuid = stat->uid;
+override_cred->fsgid = stat->gid;
+
+This is because the correct uid and gid are taken directly with the stat
+struct and correctly set with ovl_set_attr().

+Subject: [PATCH] ovl: proper cleanup of workdir
+
+When mounting overlayfs it needs a clean "work" directory under the
+supplied workdir.
+
+Previously the mount code removed this directory if it already existed and
+created a new one. If the removal failed (e.g. directory was not empty)
+then it fell back to a read-only mount not using the workdir.
+
+While this has never been reported, it is possible to get a non-empty
+"work" dir from a previous mount of overlayfs in case of crash in the
+middle of an operation using the work directory.
+
+In this case the left over state should be discarded and the overlay
+filesystem will be consistent, guaranteed by the atomicity of operations on
+moving to/from the workdir to the upper layer.
+
+This patch implements cleaning out any files left in workdir. It is
+implemented using real recursion for simplicity, but the depth is limited
+to 2, because the worst case is that of a directory containing whiteouts
+under "work".

+Subject: [PATCH] ubifs: Implement RENAME_EXCHANGE
+
+Adds RENAME_EXCHANGE to UBIFS, the operation itself
+is completely disjunct from a regular rename() that's
+why we dispatch very early in ubifs_reaname().
+
+RENAME_EXCHANGE used by the renameat2() system call
+allows the caller to exchange two paths atomically.
+Both paths have to exist and have to be on the same
+filesystem.

+Subject: [PATCH] ubifs: Use dirty_writeback_interval value for wbuf timer
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Right now wbuf timer has hardcoded timeouts and there is no place for
+manual adjustments. Some projects / cases many need that though. Few
+file systems allow doing that by respecting dirty_writeback_interval
+that can be set using sysctl (dirty_writeback_centisecs).
+
+Lowering dirty_writeback_interval could be some way of dealing with user
+space apps lacking proper fsyncs. This is definitely *not* a perfect
+solution but we don't have ideal (user space) world. There were already
+advanced discussions on this matter, mostly when ext4 was introduced and
+it wasn't behaving as ext3. Anyway, the final decision was to add some
+hacks to the ext4, as trying to fix whole user space or adding new API
+was pointless.
+
+We can't (and shouldn't?) just follow ext4. We can't e.g. sync on close
+as this would cause too many commits and flash wearing. On the other
+hand we still should allow some trade-off between -o sync and default
+wbuf timeout. Respecting dirty_writeback_interval should allow some sane
+cutomizations if used warily.

+Subject: [PATCH] softirq: let ksoftirqd do its job
+
+A while back, Paolo and Hannes sent an RFC patch adding threaded-able
+napi poll loop support : (https://patchwork.ozlabs.org/patch/620657/)
+
+The problem seems to be that softirqs are very aggressive and are often
+handled by the current process, even if we are under stress and that
+ksoftirqd was scheduled, so that innocent threads would have more chance
+to make progress.
+
+This patch makes sure that if ksoftirq is running, we let it
+perform the softirq work.
+
+Jonathan Corbet summarized the issue in https://lwn.net/Articles/687617/
+
+Tested:
+
+ - NIC receiving traffic handled by CPU 0
+ - UDP receiver running on CPU 0, using a single UDP socket.
+ - Incoming flood of UDP packets targeting the UDP socket.
+
+Before the patch, the UDP receiver could almost never get cpu cycles and
+could only receive ~2,000 packets per second.
+
+After the patch, cpu cycles are split 50/50 between user application and
+ksoftirqd/0, and we can effectively read ~900,000 packets per second,
+a huge improvement in DOS situation. (Note that more packets are now
+dropped by the NIC itself, since the BH handlers get less cpu cycles to
+drain RX ring buffer)
+
+Since the load runs in well identified threads context, an admin can
+more easily tune process scheduling parameters if needed.

+Subject: [PATCH] net: bgmac: clarify CONFIG_BCMA dependency
+
+The bgmac driver depends on BCMA_HOST_SOC, which is only used
+when CONFIG_BCMA is enabled. However, it is a bool option and can
+be set when CONFIG_BCMA=m, and then bgmac can be built-in, leading
+to an obvious link error:
+
+drivers/built-in.o: In function `bgmac_init':
+:(.init.text+0x7f2c): undefined reference to `__bcma_driver_register'
+drivers/built-in.o: In function `bgmac_exit':
+:(.exit.text+0x110a): undefined reference to `bcma_driver_unregister'
+
+To avoid this case, we need to depend on both BCMA and BCMA_SOC,
+as this patch does. I'm also trying to make the dependency more
+readable by splitting it into three lines, and adding a COMPILE_TEST
+alternative so we can test-build it in all configurations that
+support BCMA.
+
+The added dependency on FIXED_PHY addresses a related issue where
+we cannot call fixed_phy_register() when CONFIG_FIXED_PHY=m and
+CONFIG_BGMAC=y.

+
+The private structure contain a pointer to phydev, but the structure
+net_device already contain such pointer. So we can remove the pointer
+phydev in the private structure, and update the driver to use the

+Subject: [PATCH 1/5] net: ethernet: bgmac: change bgmac_* prints to dev_*
+ prints
+
+The bgmac_* print wrappers call dev_* prints with the dev pointer from
+the bcma core. In anticipation of removing the bcma requirement for
+this driver, these must be changed to not reference that struct. So,
+simply change all of the bgmac_* prints to their dev_* counterparts. In
+some cases netdev_* prints are more appropriate, so change those as
+well.

+Subject: [PATCH 2/5] net: ethernet: bgmac: add dma_dev pointer
+
+The dma buffer allocation, etc references a dma_dev device pointer from
+the bcma core. In anticipation of removing the bcma requirement for
+this driver, these must be changed to not reference that struct. Add a
+dma_dev device pointer to the bgmac stuct and reference that instead.

+Subject: [PATCH 3/5] net: ethernet: bgmac: move BCMA MDIO Phy code into a
+ separate file
+
+Move the BCMA MDIO phy into a separate file, as it is very tightly
+coupled with the BCMA bus. This will help with the upcoming BCMA
+removal from the bgmac driver. Optimally, this should be moved into
+phy drivers, but it is too tightly coupled with the bgmac driver to
+effectively move it without more changes to the driver.
+
+Note: the phy_reset was intentionally removed, as the mdio phy subsystem
+automatically resets the phy if a reset function pointer is present. In
+addition to the moving of the driver, this reset function is added.

+Date: Thu, 7 Jul 2016 19:08:56 -0400
+Subject: [PATCH 4/5] net: ethernet: bgmac: convert to feature flags
+
+The bgmac driver is using the bcma provides device ID and revision, as
+well as the SoC ID and package, to determine which features are
+necessary to enable, reset, etc in the driver. In anticipation of
+removing the bcma requirement for this driver, these must be changed to
+not reference that struct. In place of that, each "feature" has been
+given a flag, and the flags are enabled for their respective device and
+SoC.

+Date: Thu, 7 Jul 2016 19:08:57 -0400
+Subject: [PATCH 5/5] net: ethernet: bgmac: Add platform device support
+
+The bcma portion of the driver has been split off into a bcma specific
+driver. This has been mirrored for the platform driver. The last
+references to the bcma core struct have been changed into a generic
+function call. These function calls are wrappers to either the original
+bcma code or new platform functions that access the same areas via MMIO.
+This necessitated adding function pointers for both platform and bcma to
+hide which backend is being used from the generic bgmac code.

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and can
+be found in two packages (versions): BCM53573 and BCM47189. It shares
+some code with the Northstar family, but also requires some new quirks.
+
+First of all there can be up to 2 Ethernet cores on this SoC. If that is
+the case, they are connected to two different switch ports allowing some
+more complex/optimized setups. It seems the second unit doesn't come
+fully configured and requires some IRQ quirk.
+
+Other than that only the first core is connected to the PHY. For the
+second one we have to register fixed PHY (similarly to the Northstar),
+otherwise generic PHY driver would get some invalid info.
+
+This has been successfully tested on Tenda AC9 (BCM47189B0).

+It doesn't really change anything as BGMAC_CHIPCTL_1_IF_TYPE_RMII is
+equal to 0. It make code a bit clener, so far when reading it one could
+think we forgot to set a proper mode. It also keeps this mode code in

+
+This fixes regression introduced by patch adding feature flags. It was
+already reported and patch followed (it got accepted) but it appears it
+was incorrect. Instead of fixing reversed condition it broke a good one.
+
+This patch was verified to actually fix SoC hanges caused by bgmac on
+BCM47186B0.

+Subject: [PATCH 1/3] net: bgmac: allocate struct bgmac just once & don't copy
+ it
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+So far were were allocating struct bgmac in 3 places: platform code,
+bcma code and shared bgmac_enet_probe function. The reason for this was
+bgmac_enet_probe:
+1) Requiring early-filled struct bgmac
+2) Calling alloc_etherdev on its own in order to use netdev_priv later
+
+This solution got few drawbacks:
+1) Was duplicating allocating code
+2) Required copying early-filled struct
+3) Resulted in platform/bcma code having access only to unused struct
+
+Solve this situation by simply extracting some probe code into the new
+bgmac_alloc function.

+Subject: [PATCH 2/3] net: bgmac: drop struct bcma_mdio we don't need anymore
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Adding struct bcma_mdio was a workaround for bcma code not having access
+to the struct bgmac used in the core code. Now we don't duplicate this
+struct we can just use it internally in bcma code.
+
+This simplifies code & allows access to all bgmac driver details from
+all places in bcma code.

+ v4.10-rc1
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This includes following upstream commits:
+5519da874ad0 net: phy: broadcom: Move bcm54xx_auxctl_{read, write} to common library
+b14995ac2527 net: phy: broadcom: Add BCM54810 PHY entry
+5b4e29005123 net: phy: broadcom: add bcm54xx_auxctl_read
+d92ead16be40 net: phy: broadcom: Add support for BCM54612E
+3cf25904fe46 net: phy: broadcom: Update Auxiliary Control Register macros
+
+Other commits were skipped as they depend on other changes like
+ETHTOOL_PHY_DOWNSHIFT & DOWNSHIFT_DEV_DISABLE and new APIs like
+get_sset_count.
+
+One exception was picking new regs from commit d06f78c4232d ("net: phy:
+broadcom: Add support code for downshift/Wirespeed").

+Subject: [PATCH] spi: introduce accelerated read support for spi flash devices
+
+In addition to providing direct access to SPI bus, some spi controller
+hardwares (like ti-qspi) provide special port (like memory mapped port)
+that are optimized to improve SPI flash read performance.
+This means the controller can automatically send the SPI signals
+required to read data from the SPI flash device.
+For this, SPI controller needs to know flash specific information like
+read command to use, dummy bytes and address width.
+
+Introduce spi_flash_read() interface to support accelerated read
+over SPI flash devices. SPI master drivers can implement this callback to
+support interfaces such as memory mapped read etc. m25p80 flash driver
+and other flash drivers can call this make use of such interfaces. The
+interface should only be used with SPI flashes and cannot be used with
+other SPI devices.

+Subject: [PATCH] USB: core: let USB device know device node
+
+Although most of USB devices are hot-plug's, there are still some devices
+are hard wired on the board, eg, for HSIC and SSIC interface USB devices.
+If these kinds of USB devices are multiple functions, and they can supply
+other interfaces like i2c, gpios for other devices, we may need to
+describe these at device tree.
+
+In this commit, it uses "reg" in dts as physical port number to match
+the phyiscal port number decided by USB core, if they are the same,
+then the device node is for the device we are creating for USB core.

++Generic USB Device Properties
++
++Usually, we only use device tree for hard wired USB device.
++The reference binding doc is from:
++http://www.firmware.org/1275/bindings/usb/usb-1_0.ps
++
++Required properties:
++- compatible: usbVID,PID. The textual representation of VID, PID shall
++ be in lower case hexadecimal with leading zeroes suppressed. The
++ other compatible strings from the above standard binding could also
++ be used, but a device adhering to this binding may leave out all except
++ for usbVID,PID.
++- reg: the port number which this device is connecting to, the range
++ is 1-31.
++
++Example:
++
++&usb1 {
++ status = "okay";
++
++ #address-cells = <1>;
++ #size-cells = <0>;
++
++ hub: genesys@1 {
++ compatible = "usb5e3,608";
++ reg = <1>;
++ };

+Subject: [PATCH] usb/core: usb_alloc_dev(): fix setting of ->portnum
+
+With commit 69bec7259853 ("USB: core: let USB device know device node"),
+the port1 argument of usb_alloc_dev() gets overwritten as follows:
+
+ ... usb_alloc_dev(..., unsigned port1)
+ {
+ ...
+ if (!parent->parent) {
+ port1 = usb_hcd_find_raw_port_number(..., port1);
+ }
+ ...
+ }
+
+Later on, this now overwritten port1 gets assigned to ->portnum:
+
+ dev->portnum = port1;
+
+However, since xhci_find_raw_port_number() isn't idempotent, the
+aforementioned commit causes a number of KASAN splats like the following:
+
+ BUG: KASAN: slab-out-of-bounds in xhci_find_raw_port_number+0x98/0x170

+
+Fix this by not overwriting the port1 argument in usb_alloc_dev(), but
+storing the raw port number as required by OF in an additional variable,
+raw_port.

+Subject: [PATCH] clk: Add {devm_}clk_hw_{register,unregister}() APIs
+
+We've largely split the clk consumer and provider APIs along
+struct clk and struct clk_hw, but clk_register() still returns a
+struct clk pointer for each struct clk_hw that's registered.
+Eventually we'd like to only allocate struct clks when there's a
+user, because struct clk is per-user now, so clk_register() needs
+to change.
+
+Let's add new APIs to register struct clk_hws, but this time
+we'll hide the struct clk from the caller by returning an int
+error code. Also add an unregistration API that takes the clk_hw
+structure that was passed to the registration API. This way
+provider drivers never have to deal with a struct clk pointer
+unless they're using the clk consumer APIs.

+Subject: [PATCH] clk: Add clk_hw OF clk providers
+
+Now that we have a clk registration API that doesn't return
+struct clks, we need to have some way to hand out struct clks via
+the clk_get() APIs that doesn't involve associating struct clk
+pointers with an OF node. Currently we ask the OF provider to
+give us a struct clk pointer for some clkspec, turn that struct
+clk into a struct clk_hw and then allocate a new struct clk to
+return to the caller.
+
+Let's add a clk_hw based OF provider hook that returns a struct
+clk_hw directly, so that we skip the intermediate step of
+converting from struct clk to struct clk_hw. Eventually when
+we've converted all OF clk providers to struct clk_hw based APIs
+we can remove the struct clk based ones.
+
+It should also be noted that we change the onecell provider to
+have a flex array instead of a pointer for the array of clk_hw
+pointers. This allows providers to allocate one structure of the
+correct length in one step instead of two.

+Subject: [PATCH] usb: core: Introduce a USB port LED trigger
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This commit adds a new trigger responsible for turning on LED when USB
+device gets connected to the selected USB port. This can can useful for
+various home routers that have USB port(s) and a proper LED telling user
+a device is connected.
+
+The trigger gets its documentation file but basically it just requires
+enabling it and selecting USB ports (e.g. echo 1 > ports/usb1-1).
+
+There was a long discussion on design of this driver. Its current state
+is a result of picking them most adjustable solution as others couldn't
+handle all cases.
+
+1) It wasn't possible for the driver to register separated trigger for
+ each USB port. Some physical USB ports are handled by more than one
+ controller and so by more than one USB port. E.g. USB 2.0 physical
+ port may be handled by OHCI's port and EHCI's port.
+ It's also not possible to assign more than 1 trigger to a single LED
+ and implementing such feature would be tricky due to syncing triggers
+ and sysfs conflicts with old triggers.
+
+2) Another idea was to register trigger per USB hub. This wouldn't allow
+ handling devices with multiple USB LEDs and controllers (hubs)
+ controlling more than 1 physical port. It's common for hubs to have
+ few ports and each may have its own LED.
+
+This final trigger is highly flexible. It allows selecting any USB ports
+for any LED. It was also modified (comparing to the initial version) to
+allow choosing ports rather than having user /guess/ proper names. It
+was successfully tested on SmartRG SR400ac which has 3 USB LEDs,
+2 physical ports and 3 controllers.
+
+It was noted USB subsystem already has usb-gadget and usb-host triggers
+but they are pretty trivial ones. They indicate activity only and can't
+have ports specified.
+
+In future it may be good idea to consider adding activity support to
+usbport as well. This should allow switching to this more generic driver
+and maybe marking old ones as obsolete.
+This can be implemented with another sysfs file for setting mode. The
+default mode wouldn't change so there won't be ABI breakage and so such
+feature can be safely implemented later.
+
+There was also an idea of supporting other devices (PCI, SDIO, etc.) but
+as this driver already contains some USB specific code (and will get
+more) these should be probably separated drivers (triggers).

++USB port LED trigger
++====================
++
++This LED trigger can be used for signalling to the user a presence of USB device
++in a given port. It simply turns on LED when device appears and turns it off
++when it disappears.
++
++It requires selecting USB ports that should be observed. All available ones are
++listed as separated entries in a "ports" subdirectory. Selecting is handled by
++echoing "1" to a chosen port.
++
++Please note that this trigger allows selecting multiple USB ports for a single
++LED. This can be useful in two cases:
++
++1) Device with single USB LED and few physical ports
++
++In such a case LED will be turned on as long as there is at least one connected
++USB device.
++
++2) Device with a physical port handled by few controllers
++
++Some devices may have one controller per PHY standard. E.g. USB 3.0 physical
++port may be handled by ohci-platform, ehci-platform and xhci-hcd. If there is
++only one LED user will most likely want to assign ports from all 3 hubs.
++
++
++This trigger can be activated from user space on led class devices as shown
++below:
++
++ echo usbport > trigger
++
++This adds sysfs attributes to the LED that are documented in:
++Documentation/ABI/testing/sysfs-class-led-trigger-usbport
++
++Example use-case:
++
++ echo usbport > trigger
++ echo 1 > ports/usb1-port1
++ echo 1 > ports/usb2-port1
++ cat ports/usb1-port1
++ echo 0 > ports/usb1-port1

+Subject: [PATCH] leds: leds-gpio: Set of_node for created LED devices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When working with Device Tree we iterate over children of "gpio-leds"
+compatible node and create LED device for each of them. We take care of
+all common DT properties (label, default trigger, state, etc.), however
+some triggers may want to support more of them.
+
+It could be useful for timer trigger to support setting delay on/off
+values with Device Tree property. Or for transient trigger to support
+e.g. duration property.
+
+We obviously should handle such properties in triggers, not in generic
+code. To let trigger drivers read properties from DT node we need to set
+of_node to point the relevant node. This change allows using all kind of
+of helpers in e.g. "activate" callbacks.

+Subject: [PATCH] regmap: make LZO cache optional
+
+Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support
+for LZO compression in regcache, but there were never any users added
+afterwards. Since LZO support itself has its own size, it currently is
+rather a deoptimization.
+
+So make it optional by introducing a symbol that can be selected by
+drivers wanting to make use of it.
+
+Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).

+I tried using google to find any users (even out-of-tree ones), but at
+best I found a single driver submission that was switched to RBTREE in
+subsequent resubmissions (MFD_SMSC).
+
+One could maybe also just drop the code because of no users for 5 years,
+but that would be up to the maintainer(s) to decide.

+Subject: [PATCH] MIPS: c-r4k: Use IPI calls for CM indexed cache ops
+
+The Coherence Manager (CM) can propagate address-based ("hit") cache
+operations to other cores in the coherent system, alleviating software
+of the need to use IPI calls, however indexed cache operations are not
+propagated since doing so makes no sense for separate caches.
+
+r4k_on_each_cpu() previously had a special case for CONFIG_MIPS_MT_SMP,
+intended to avoid the IPIs when the only other CPUs in the system were
+other VPEs in the same core, and hence sharing the same caches. This was
+changed by commit cccf34e9411c ("MIPS: c-r4k: Fix cache flushing for MT
+cores") to apparently handle multi-core multi-VPE systems, but it
+focussed mainly on hit cache ops, so the IPI calls were still disabled
+entirely for CM systems.
+
+This doesn't normally cause problems, but tests can be written to hit
+these corner cases by using multiple threads, or changing task
+affinities to force the process to migrate cores. For example the
+failure of mprotect RW->RX to globally sync icaches (via
+flush_cache_range) can be detected by modifying and mprotecting a code
+page on one core, and migrating to a different core to execute from it.
+
+Most of the functions called by r4k_on_each_cpu() perform cache
+operations exclusively with a single addressing-type (virtual address vs
+indexed), so add a type argument and modify the callers to pass in
+R4K_USER (user virtual addressing), R4K_KERN (global kernel virtual
+addressing) or R4K_INDEX (index into cache).
+
+local_r4k_flush_icache_range() is split up, to allow it to be called
+from the rest of the kernel, or from r4k_flush_icache_range() where it
+will choose either indexed or hit cache operations based on the size of
+the range and the cache sizes.
+
+local_r4k_flush_kernel_vmap_range() is split into two functions, each of
+which uses cache operations with a single addressing-type, with
+r4k_flush_kernel_vmap_range() making the decision whether to use indexed
+cache ops or not.

+Subject: [PATCH] MIPS: store the appended dtb address in a variable
+
+Instead of rewriting the arguments to match the UHI spec, store the
+address of a appended or UHI supplied dtb in fw_supplied_dtb.
+
+That way the original bootloader arugments are kept intact while still
+making the use of an appended dtb invisible for mach code.
+
+Mach code can still find out if it is an appended dtb by comparing
+fw_arg1 with fw_supplied_dtb.

+ icache flushes
+
+Commit f70ddc07b637 ("MIPS: c-r4k: Avoid small flush_icache_range SMP
+calls") adds checks to force use of hit-type cache ops for small icache
+flushes where they are globalised & index-type cache ops aren't, in
+order to avoid the overhead of IPIs in those cases. However it
+calculated the size of the region being flushed incorrectly, subtracting
+the end address from the start address rather than the reverse. This
+would have led to an overflow with size wrapping round to some large
+value, and likely to the special case for avoiding IPIs not actually
+being hit.

+As it was discussed quite some time ago (see

+"model" property in .dts. Moreover as per ePAPR "model" property is

+
+This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
+page_to_pfn anymore.
+
+The following output was generated with two hacked in printk statements:
+
+printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
+(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
+ if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
+ mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
+printk("after %p\n", mem_map);
+
+Output:
+
+[ 0.000000] before 8861b280 vs. 8861b280 or 8851b280
+[ 0.000000] after 8851b280
+
+As seen in the first line mem_map with subtraction of offset does not equal the
+mem_map after subtraction of ARCH_PFN_OFFSET.
+
+After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
+previously calculated offset is zero for the named platform it is able to boot
+4.4 and 4.9-rc7 again.

+Subject: bridge: allow receiption on disabled port
+
+When an ethernet device is enslaved to a bridge, and the bridge STP

+
+This breaks control applications like WPA which maybe expecting to

+Several DMA ops are no-op on many platforms, and the indirection through
+the mips_dma_map_ops function table is causing the compiler to emit
+unnecessary code.
+
+Inlining visibly improves network performance in my tests (on a 24Kc

+Subject: [PATCH 2/3] mtd: part: add generic parsing of linux,part-probe
+
+This moves the linux,part-probe device tree parsing code from
+physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
+providing a reference to their device tree node in struct
+mtd_part_parser_data.

+Subject: [PATCH] usb: gadget: net2280: add USB2380 support
+
+The PLX USB2380 is a PCIe version of the NET2280 and behaves more like the
+USB338x but without the USB3.0 superspeed support.
+
+This was tested with g_ether, g_serial, g_mass_storage on a Gateworks
+Ventana GW2383.

+Subject: [PATCH] Revert "bcma: init serial console directly from ChipCommon
+ code"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit 4c81acab3816 ("bcma: init serial console directly
+from ChipCommon code") as it broke IRQ assignment. Getting IRQ with
+bcma_core_irq helper on SoC requires MIPS core to be set. It happens
+*after* ChipCommon initialization so we can't do this so early.
+
+This fixes a user reported regression. It wasn't critical as serial was
+still somehow working but lack of IRQs was making in unreliable.
+
+Fixes: 4c81acab3816 ("bcma: init serial console directly from ChipCommon code")

+Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
+
+including sysinfo.h from kernel.h makes no sense whatsoever,
+but removing it breaks glibc's userspace header,
+which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
+this seems to be a historical mistake.
+on musl, including any header that uses kernel.h directly or indirectly
+plus sys/sysinfo.h will produce a compile error due to redefinition of
+struct sysinfo from sys/sysinfo.h.
+so for now, only include it on glibc or when including from kernel
+in order not to break their headers.

+Subject: [PATCH 2/3] uapi/libc-compat.h: do not rely on __GLIBC__
+
+Musl provides the same structs as glibc, but does not provide a define to
+allow its detection. Since the absence of __GLIBC__ also can mean that it
+is included from the kernel, change the __GLIBC__ detection to
+!__KERNEL__, which should always be true when included from userspace.

+Message-Id: <1396868224-252888-2-git-send-email-manuel.lauss@gmail.com>
+
+This small patch makes the MIPS FPU emulator optional. The kernel
+kills float-users on systems without a hardware FPU by sending a SIGILL.
+
+Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
+optimizing for size).

+v4: rediffed because of patch 1/2, should now work with micromips as well
+v3: updated patch description with size savings.
+v2: incorporated changes suggested by Jonas Gorski
+ force the fpu emulator on for micromips: relocating the parts
+ of the mmips code in the emulator to other areas would be a
+ much larger change; I went the cheap route instead with this.

+Subject: [PATCH 1/2] openwrt: arc - remove dependency on DEVTMPFS
+
+OpenWRT builds initramfs so that it doesn't require DEVTMPFS so dropping
+this dependency. That helps to escape 2 separate kernel rebuilds with
+and without initramfs.
+
+2 builds happen because OpenWRT first builds kernel and later modules.
+When building entire kernel with simple "make" INITRAMFS sets to a real
+value and so was triggering DEVTMPFS selection. Then when building only
+modules with "make modules" command INITRAMFS is zeroed and so kernel
+config was changing that lead to full kernel rebuild.

+Subject: [PATCH 2/2] openwrt: arc - add OWRTDTB section
+
+This change allows OpenWRT to patch resulting kernel binary with
+external .dtb.
+
+That allows us to re-use exactky the same vmlinux on different boards
+given its ARC core configurations match (at least cache line sizes etc).
+
+""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
+.dtb right after it, keeping the string in place.

+
+This enables misaligned access handling even in kernel mode.
+Some wireless drivers (ath9k-htc and mt7601u) use misaligned accesses
+here and there and to cope with that without fixing stuff in the drivers
+we're just gracefully handling it on ARC.

++ MyLoader is a bootloader which allows the user to define partitions

++ on the device, similar to a partition table. This table gives the
++ offsets and lengths of the user defined partitions.
++
++ If you need code which can detect and parse these tables, and
++ register MTD 'partitions' corresponding to each image detected,
++ enable this option.
++
++ You will still need the parsing functions to be called by the driver
++ for your particular device. It won't happen automatically.

+Subject: [PATCH] Add support for MAP-E FMRs (mesh mode)
+
+MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
+between MAP CEs (mesh mode) without the need to forward such data to a
+border relay. This is similar to how 6rd works but for IPv4 over IPv6.

+Subject: [PATCH 1/2] ipv6: allow rejecting with "source address failed policy"
+
+RFC6204 L-14 requires rejecting traffic from invalid addresses with
+ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
+egress policy) on the LAN side, so add an appropriate rule for that.

+Subject: NET: skip GRO for foreign MAC addresses
+
+For network drivers using napi_gro_receive, packets are run through GRO,
+even when the destination MAC address does not match, and they're supposed
+to be delivered to another host behind a different bridge port.
+
+This can be very expensive, because for drivers without TSO or scatter-
+gather, this can only be undone by copying the skb and checksumming it
+again.
+
+To be able to track foreign MAC addresses in an inexpensive way, create
+a mask of changed bits in MAC addresses of upper devices. This allows
+handling VLANs and bridge devices with different addresses (as long as
+they are not too different).

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The driver of course "knows" that the chip's reset signal is active low,
+so it drives the GPIO to 0 to reset the PHY and to 1 otherwise; however
+all this will only work iff the GPIO is specified as active-high in the
+device tree! I think both the driver and the device trees (if there are
+any -- I was unable to find them) need to be fixed in this case...

+Subject: [PATCH] net: phy: at803x: Request 'reset' GPIO only for AT8030 PHY
+
+This removes the dependency on GPIOLIB for non faulty PHYs.
+
+Indeed, without this patch, if GPIOLIB is not selected
+devm_gpiod_get_optional() will return -ENOSYS and the driver probe
+call will fail, regardless of the actual PHY hardware.
+
+Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035),
+only AT8030 presents the issues that commit 13a56b449325 ("net: phy:
+at803x: Add support for hardware reset") attempts to work-around by
+using a 'reset' GPIO line.
+
+Hence, only AT8030 should depend on GPIOLIB operating properly.
+

+ link change
+
+Commit 13a56b44 ("at803x: Add support for hardware reset") added a
+work-around for a hardware bug on the AT8030. However, the work-around
+was being called for all 803x PHYs, even those that don't need it.
+Function at803x_link_change_notify() checks to make sure that it only
+resets the PHY on the 8030, but it makes more sense to not call that
+function at all if it isn't needed.

+
+There're some discussions in mailing lists proposing to disable
+that particular check alltogether and magically all seem to work
+fine with muted warning.
+
+Anyways new thread on that regard could be found here:
+http://lists.infradead.org/pipermail/linux-snps-arc/2016-July/001310.html
+
+Let's see what comes out of that new discussion, hopefully patching
+of generic USB stuff won't be required then.

+Subject: [PATCH] libata: add ledtrig support
+To: linux-ide@vger.kernel.org,
+ Tejun Heo <tj@kernel.org>
+
+This adds a LED trigger for each ATA port indicating disk activity.
+
+As this is needed only on specific platforms (NAS SoCs and such),
+these platforms should define ARCH_WANTS_LIBATA_LEDS if there
+are boards with LED(s) intended to indicate ATA disk activity and
+need the OS to take care of that.
+In that way, if not selected, LED trigger support not will be
+included in libata-core and both, codepaths and structures remain
+untouched.

+From: Felix Fietkau <nbd@nbd.name>
+Subject: MIPS: fix cache flushing for highmem pages
+
+Most cache flush ops were no-op for highmem pages. This led to nasty
+segfaults and (in the case of page_address(page) == NULL) kernel
+crashes.
+
+Fix this by always flushing highmem pages using kmap/kunmap_atomic
+around the actual cache flush. This might be a bit inefficient, but at
+least it's stable.

+
+This patch adds an ignore_oc flag which can be set by EHCI controller
+not supporting or wanting to disable overcurrent checking. The EHCI
+platform data in include/linux/usb/ehci_pdriver.h is also augmented to
+take advantage of this new flag.

+
+This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
+page_to_pfn anymore.
+
+The following output was generated with two hacked in printk statements:
+
+printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
+(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
+ if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
+ mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
+printk("after %p\n", mem_map);
+
+Output:
+
+[ 0.000000] before 8861b280 vs. 8861b280 or 8851b280
+[ 0.000000] after 8851b280
+
+As seen in the first line mem_map with subtraction of offset does not equal the
+mem_map after subtraction of ARCH_PFN_OFFSET.
+
+After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
+previously calculated offset is zero for the named platform it is able to boot
+4.4 and 4.9-rc7 again.

+Subject: uapi/kernel.h: glibc specific inclusion of sysinfo.h
+
+including sysinfo.h from kernel.h makes no sense whatsoever,
+but removing it breaks glibc's userspace header,
+which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
+this seems to be a historical mistake.
+on musl, including any header that uses kernel.h directly or indirectly
+plus sys/sysinfo.h will produce a compile error due to redefinition of
+struct sysinfo from sys/sysinfo.h.
+so for now, only include it on glibc or when including from kernel
+in order not to break their headers.

+Subject: [RFC PATCH v4 2/2] MIPS: make FPU emulator optional
+
+This small patch makes the MIPS FPU emulator optional. The kernel
+kills float-users on systems without a hardware FPU by sending a SIGILL.
+
+Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
+optimizing for size).
+
+Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com>
+---
+v4: rediffed because of patch 1/2, should now work with micromips as well
+v3: updated patch description with size savings.
+v2: incorporated changes suggested by Jonas Gorski
+ force the fpu emulator on for micromips: relocating the parts
+ of the mmips code in the emulator to other areas would be a
+ much larger change; I went the cheap route instead with this.

++ ---help---
++ MyLoader is a bootloader which allows the user to define partitions
++ in flash devices, by putting a table in the second erase block
++ on the device, similar to a partition table. This table gives the
++ offsets and lengths of the user defined partitions.
++
++ If you need code which can detect and parse these tables, and
++ register MTD 'partitions' corresponding to each image detected,
++ enable this option.
++
++ You will still need the parsing functions to be called by the driver
++ for your particular device. It won't happen automatically.

+Subject: kernel: disable cfi cmdset 0002 erase suspend
+
+on some platforms, erase suspend leads to data corruption and lockups when write
+ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
+rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
+simply disable erase suspend, as it will usually not produce any useful gain on
+the small filesystems used on embedded hardware.

+Subject: Add support for MAP-E FMRs (mesh mode)
+
+MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
+between MAP CEs (mesh mode) without the need to forward such data to a
+border relay. This is similar to how 6rd works but for IPv4 over IPv6.

+Subject: ipv6: allow rejecting with "source address failed policy"
+
+RFC6204 L-14 requires rejecting traffic from invalid addresses with
+ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
+egress policy) on the LAN side, so add an appropriate rule for that.

+
+Many embedded devices have information such as mac addresses stored inside mtd
+devices. This patch allows us to add a property inside a node describing a
+network interface. The new property points at a mtd partition with an offset
+where the mac address can be found.

+Subject: libata: add ledtrig support
+
+This adds a LED trigger for each ATA port indicating disk activity.
+
+As this is needed only on specific platforms (NAS SoCs and such),
+these platforms should define ARCH_WANTS_LIBATA_LEDS if there
+are boards with LED(s) intended to indicate ATA disk activity and
+need the OS to take care of that.
+In that way, if not selected, LED trigger support not will be
+included in libata-core and both, codepaths and structures remain
+untouched.
