-Subject: [PATCH] AR7/cpmac: convert to new fixed phy infrastructure, now for real
-
-This patch converts platform code to register fixed phys early.
-cpmac driver modified to blindly accept fixed phy id (that is equal
-to platform device id).

-From: Anton Vorontsov <avorontsov@ru.mvista.com>
-Date: Wed, 5 Mar 2008 14:52:26 +0300
-Subject: [PATCH] AR7/cpmac: convert to new fixed phy infrastructure, now for real
-
-This patch converts platform code to register fixed phys early.
-cpmac driver modified to blindly accept fixed phy id (that is equal
-to platform device id).

-+ select ZLIB_INFLATE
-+ help
-+ Saying Y here includes support for SquashFS 3.0 (a Compressed Read-Only File
-+ System). Squashfs is a highly compressed read-only filesystem for Linux.
-+ It uses zlib compression to compress both files, inodes and directories.
-+ Inodes in the system are very small and all blocks are packed to minimise
-+ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
-+ SquashFS 3.0 supports 64 bit filesystems and files (larger than 4GB), full
-+ uid/gid information, hard links and timestamps.
-+
-+ Squashfs is intended for general read-only filesystem use, for archival
-+ use (i.e. in cases where a .tar.gz file may be used), and in embedded
-+ systems where low overhead is needed. Further information and filesystem tools
-+ are available from http://squashfs.sourceforge.net.
-+
-+ If you want to compile this as a module ( = code which can be
-+ inserted in and removed from the running kernel whenever you want),
-+ say M here and read <file:Documentation/modules.txt>. The module
-+ will be called squashfs. Note that the root file system (the one
-+ containing the directory /) cannot be compiled as a module.

-+ By default SquashFS caches the last 3 fragments read from
-+ the filesystem. Increasing this amount may mean SquashFS
-+ has to re-read fragments less often from disk, at the expense
-+ of extra system memory. Decreasing this amount will mean
-+ SquashFS uses less memory at the expense of extra reads from disk.
-+
-+ Note there must be at least one cached fragment. Anything
-+ much more than three will probably not make much difference.

-+config SQUASHFS_VMALLOC
-+ bool "Use Vmalloc rather than Kmalloc" if SQUASHFS_EMBEDDED

-+ help
-+ By default SquashFS uses kmalloc to obtain fragment cache memory.
-+ Kmalloc memory is the standard kernel allocator, but it can fail
-+ on memory constrained systems. Because of the way Vmalloc works,
-+ Vmalloc can succeed when kmalloc fails. Specifying this option
-+ will make SquashFS always use Vmalloc to allocate the
-+ fragment cache memory.

-+ * together with their "next" pointers, since precedence prevents
-+ * anything being concatenated to any individual branch. The
-+ * "next" pointer of the last BRANCH in a choice points to the
-+ * thing following the whole choice. This is also where the
-+ * final "next" pointer of each individual branch points; each
-+ * branch starts with the operand node of a BRANCH node.
-+ *
-+ * BACK Normal "next" pointers all implicitly point forward; BACK
-+ * exists to make loop structures possible.
-+ *
-+ * STAR,PLUS '?', and complex '*' and '+', are implemented as circular
-+ * BRANCH structures using BACK. Simple cases (one character
-+ * per match) are implemented with STAR and PLUS for speed
-+ * and to minimize recursive plunges.
-+ *
-+ * OPEN,CLOSE ...are numbered at compile time.
-+ */

-+ * A node is one char of opcode followed by two chars of "next" pointer.

-+ * value is a positive offset from the opcode of the node containing it.
-+ * An operand, if any, simply follows the node. (Note that much of the
-+ * code generation knows about this implicit relationship.)

-+ *
-+ * The first version was written by Martin Devera, <devik@cdi.cz>
-+ *
-+ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
-+ * - Update patch to 2.4.21
-+ * Sebastian Strollo <sstrollo@nortelnetworks.com>
-+ * - Fix "Dead-loop on netdevice imq"-issue
-+ * Marcel Sebek <sebek64@post.cz>
-+ * - Update to 2.6.2-rc1
-+ *
-+ * After some time of inactivity there is a group taking care
-+ * of IMQ again: http://www.linuximq.net
-+ *
-+ *
-+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7 including
-+ * the following changes:
-+ *
-+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
-+ * - Correction of imq_init_devs() issue that resulted in
-+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
-+ * - Addition of functionality to choose number of IMQ devices
-+ * during kernel config (Andre Correa)
-+ * - Addition of functionality to choose how IMQ hooks on
-+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
-+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
-+ *
-+ *
-+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
-+ * released with almost no problems. 2.6.14-x was released
-+ * with some important changes: nfcache was removed; After
-+ * some weeks of trouble we figured out that some IMQ fields
-+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
-+ * These functions are correctly patched by this new patch version.
-+ *
-+ * Thanks for all who helped to figure out all the problems with
-+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
-+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
-+ * I didn't forget anybody). I apologize again for my lack of time.

-+2006-01-24 Markus Klotzbuecher <mk@mary.denx.de>
-+
-+ * Add tons of ugly ifdefs to Ed L. Cashin's mutex patch to
-+ retain backwards compatibility.
-+
-+2006-01-24 Ed L. Cashin <ecashin@coraid.com>
-+
-+ * Support for the new mutex infrastructure
-+ (7892f2f48d165a34b0b8130c8a195dfd807b8cb6)
-+
-+2005-10-15 Markus Klotzbuecher <mk@localhost.localdomain>
-+
-+ * Bugfix for a serious memory leak in mini_fo_follow_link.
-+
-+2005-09-21 Markus Klotzbuecher <mk@mary>
-+
-+ * new release 0.6.1
-+
-+ * fix of a compiler warning due to changes in 2.6.13
-+
-+2005-09-21 Klaus Wenninger <klaus.wenninger@siemens.com>
-+
-+ * file.c: readdir: fix for a bug that caused directory entries
-+ to show up twice when using storage filesystems such as
-+ minixfs or pramfs.
-+
-+2005-06-30 Eric Lammerts <eric@lammerts.org>
-+
-+ * fix for an oops when overwriting a binary thats beeing
-+ executed.
-+
-+2005-06-09 <mk@mary>
-+
-+ * Renamed overlay to mini_fo-overlay.
-+
-+ * Added mini_fo-merge script to allow merging of storage and base
-+ after making modifications.
-+
-+2005-05-22 root <mk@mary>
-+
-+ * Added overlay script that allows to easily mount mini_fo ontop
-+ of a given base directory
-+
-+2005-05-10 <mk@mary>
-+
-+ * inode.c: xattr functions return -EOPNOSUPP instead of
-+ -ENOSUPP, what confuses "ls -l"
-+
-+ * Changed license from LGPL to GPL.
-+
-+2005-05-08 root <mk@mary>
-+
-+ * Makefile: clean it up and added make install and make
-+ uninstall.
-+
-+2005-05-06 <mk@mary>
-+
-+ * merged devel branch back to main. [v0-6-0-pre3]
-+
-+ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
-+
-+ * ioctl: removed fist_ioctl stuff, that is not needed for
-+ now.
-+
-+2005-05-03 <mk@mary>
-+
-+ * file.c: simplified mini_fo_open and mini_fo_setattr using
-+ new state changing functions. [devel-0-0-17]
-+
-+ * inode.c: Fixed getattr state bug (see below) in 2.4 function
-+ mini_fo_inode revalidate.
-+
-+ * inode.c: found an other bug in mini_fo_getattr. States are not
-+ reliable in this function, as a file can be opened, unlinked and
-+ the getattr function called. This results in a deleted dentry
-+ with an inode. Fix is to ignore states and simply use the inode
-+ available.
-+
-+2005-04-29 <mk@mary>
-+
-+ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
-+
-+ * file.c: do not use mini_fo_lock so the generic version is
-+ used (I guess).
-+
-+ * inode.c: getattr, never call getattr on lower files, as this
-+ will cause the inum to change.
-+
-+ * inode.c: rename_reg_file renamed to rename_nondir, as it
-+ doesn't matter as long it't not a dir. Removed all
-+ rename_dev_file etc.
-+
-+ * tagged as devel-0-0-15
-+
-+ * inode.c: added support for chosing support for extended
-+ attrs at compile time by XATTR define in mini_fo.h .
-+
-+ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
-+ lower again, what avoids inode number changes that confused
-+ rm again. This is the proper solution.
-+
-+2005-04-24 <mk@mary>
-+
-+ * all files: updated Copyright notive to 2005. [devel-0-0-14]
-+
-+ * inode.c: fixed mini_fo_getattr to not change the inode
-+ number, even if lower files change.
-+
-+ * super.c: fixed a bug that caused deleted base file to show
-+ up suddenly after some time, or after creating a special
-+ file. The problem was that after some time or after special
-+ file creating sync_sb_inodes is called by the vfs, that
-+ called our mini_fo_put_inode. There was (wrongly) called
-+ __meta_put_lists, that nuked the lists, although the inode
-+ was going to continue its life. Moving __meta_put_lists to
-+ mini_fo_clear_inode, where an inode is really destroyed,
-+ solved the problem.
-+
-+
-+2005-04-23 <mk@mary>
-+
-+ * state.c, aux.c: more cleaning up and
-+ simplifications. [devel-0-0-13]
-+
-+ * inode.c: implemented mini_fo_getattr, that was required for
-+ 2.6 because inode_revalidate has been remove there, and the
-+ old "du" bug returned.
-+
-+
-+2005-04-20 <mk@mary>
-+
-+ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
-+ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
-+
-+2005-04-19 <mk@mary>
-+
-+ * Fixed a bug under 2.6 that caused files deleted via mini_fo
-+ not to be deleted properly and therefore the fs filled up
-+ untill no memory was left. [devel-0-0-12]
-+
-+ * Added basic hard link support. This means that creating
-+ hardlinks will work, but existing ones will be treated as
-+ individual files. [devel-0-0-11]
-+
-+2005-04-17 <mk@mary>
-+
-+ * Bugfixes
-+
-+2005-04-13 root <mk@mary>
-+
-+ * Added file state.c for the state transition
-+ functions. Doesn't work very well yet, though...
-+
-+2005-04-12 <mk@mary>
-+
-+ * Porting to 2.6 started, which is easier than expected, also
-+ due to Olivier previous work.
-+
-+2005-04-08 <mk@mary>
-+
-+ * Fixed the bug that caused du to return invalid sizes of
-+ directory trees. The problem was that
-+ mini_fo_inode_revalidate didn't always copy the attributes
-+ from the base inode properly.
-+
-+2005-04-01 Markus Klotzbuecher <mk@chasey>
-+
-+ * Merged devel branch back to main trunk and updated the
-+ RELEASE notes. This will be 0-6-0-pre1.
-+
-+2005-03-31 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed some bugs in rename_reg_file, that only showed up in
-+ the kernel compile test. Kernel compiles cleanly ontop of
-+ mini_fo, now also make mrproper etc. work. Seems pretty stable.
-+
-+2005-03-28 Markus Klotzbuecher <mk@chasey>
-+
-+ * Many, many directory renaming bugfixes and a lot of other
-+ cleanup. Dir renaming seems to work relatively stable.
-+
-+2005-03-22 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing lightweight directory renaming. Some
-+ basic testing indicates it works fine.
-+ Next is to implement testcases for the testsuite and confirm
-+ everything is really working ok.
-+
-+2005-03-18 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing meta.c stuff required for directory
-+ renaming.
-+
-+2005-03-17 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed all compile warnings + an extremly old bug that
-+ somehow crept in while reworking the wol stuff to the META
-+ system. Turning on -Werror again... :-)
-+
-+ * Fixed some bugs in the new rename_reg_file function.
-+
-+ * Rewrote mini_fo rename and split it into several
-+ subfunctions, that handle the different types
-+ seperately. Rewrote the regular file function aswell, as it
-+ was implemented somewhat inefficient.
-+
-+2005-03-16 Markus Klotzbuecher <mk@chasey>
-+
-+ * Implemented new META subsystem, removed old WOL stuff in favor
-+ if it.
-+
-+ * After some basic testing everything seems ok...
-+
-+2005-03-11 Markus Klotzbuecher <mk@chasey>
-+
-+ * Renaming a non regular file caused trouble because I always
-+ tried to copy the contents. Now I only do this for regular
-+ files. mini_fo_rename still isn't implemented properly, renaming
-+ of device files, symlinks etc. results in a empty regular file
-+ instead of the proper type.
-+
-+ * Directory renaming suddenly works! What a surprise! I guess
-+ this is because renaming is implemented as making a copy and
-+ removing the original. Still this might not work
-+ everywhere...
-+
-+2005-03-09 Markus Klotzbuecher <mk@chasey>
-+
-+ * Bugfix, when a mini_fo directory that exists in storage
-+ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
-+ possibly existing WOL file contained in it needs to be
-+ deleted too.
-+
-+ * Starting cleanup: defined state names in order to get rid of
-+ the state numbers.
-+
-+2005-03-08 Markus Klotzbuecher <mk@chasey>
-+
-+ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
-+
-+ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
-+ DEL_REWRITTEN the hash was calculated from the base dentry,
-+ which was wrong and and caused assertions in
-+ __mini_fo_hidden_dentry to fail.
-+
-+2005-02-21 <mk@mary>
-+
-+ * Implemented directory deleting (inode.c)
-+
-+ * main.c: made mini_fo_parse_options a little more robust.
-+
-+2004-12-22 <mk@mary>
-+
-+ * Makefile cleanup and uml stuff, removed unneccessary files
-+
-+ * Created a new and hopefully more informative README
-+
-+ * CHANGELOG: created a new CHANGELOG and added old entries reversely
-+
-+
-+2004-10-24 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Fix: owner and group where not correctly copied from base to
-+ storage.
-+
-+
-+2004-10-05 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of fsync, fasync and lock mini_fo functions.
-+
-+
-+2004-09-29 Bob Lee <bob@pantasys.com>
-+
-+ * Fix of a serious pointer bug
-+
-+
-+2004-09-28 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of mini_fo_mknod and mini_fo_rename, support
-+ for device files.

-+README for the mini_fo overlay file system
-+=========================================
-+
-+
-+WHAT IS MINI_FO?
-+----------------
-+
-+mini_fo is a virtual kernel file system that can make read-only
-+file systems writable. This is done by redirecting modifying operations
-+to a writeable location called "storage directory", and leaving the
-+original data in the "base directory" untouched. When reading, the
-+file system merges the modifed and original data so that only the
-+newest versions will appear. This occurs transparently to the user,
-+who can access the data like on any other read-write file system.
-+
-+Base and storage directories may be located on the same or on
-+different partitions and may be of different file system types. While
-+the storage directory obviously needs to be writable, the base may or
-+may not be writable, what doesn't matter as it will no be modified
-+anyway.
-+
-+
-+WHAT IS GOOD FOR?
-+-----------------
-+
-+The primary purpose of the mini_fo file system is to allow easy
-+software updates to embedded systems, that often store their root
-+file system in a read-only flash file system, but there are many
-+more as for example sandboxing, or for allowing live-cds to
-+permanently store information.
-+
-+
-+BUILDING
-+--------
-+This should be simple. Adjust the Makefile to point to the correct
-+kernel headers you want to build the module for. Then:
-+
-+ # make
-+
-+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
-+kernel.
-+
-+If you are building the module for you current kernel, you can install
-+the module (as root):
-+
-+ # make install
-+
-+or uninstall with
-+
-+ # make uninstall
-+
-+
-+USING THE FILE SYSTEM
-+--------------------
-+
-+the general mount syntax is:
-+
-+ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
-+ <base directory> <mount point>
-+
-+Example:
-+
-+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
-+on it:
-+
-+load the module (as root)
-+
-+ # insmod mini_fo.o for a 2.4 kernel or
-+
-+ # insmod mini_fo.ko for a 2.6 kernel
-+
-+
-+create a storage dir in tmp and a mountpoint for mini_fo:
-+
-+ # mkdir /tmp/sto
-+ # mkdir /mnt/mini_fo
-+
-+and mount the mini_fo file system:
-+
-+ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
-+
-+
-+Now the data stored on the cd can be accessed via the mini_fo
-+mountpoint just like any read-write file system, files can be modified
-+and deleted, new ones can be created and so on. When done unmount the
-+file system:
-+
-+ # unmount /mnt/mini_fo
-+
-+Note that if the file system is mounted again using the same storage
-+file system, of course it will appear in the modified state again. If
-+you remount it using an new empty storage directory, it will be
-+unmodified. Therefore by executing:
-+
-+ # cd /tmp/sto
-+ # rm -rf *
-+
-+you can nuke all the changes you made to the original file system. But
-+ remember NEVER do this while the mini_fo file system is mounted!
-+
-+
-+Alternatively you can use the mini_fo-overlay bash script, that
-+simplifies managing mini_fo mounts. See TOOLS Section.
-+
-+
-+TOOLS
-+-----
-+
-+mini_fo-merge (experimental):
-+
-+This is a bash script that will merge changes contained in the storage
-+directory back to the base directory. This allows mini_fo to function
-+as a cache file system by overlaying a slow (network, ...) file system
-+and using a fast (ramdisk, ...) as storage. When done, changes can be
-+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
-+-h" for details.
-+
-+It can be usefull for merging changes back after a successfull test
-+(patches, software updates...)
-+
-+
-+mini_fo-overlay:
-+
-+This bash script simplifies managing one or more mini_fo mounts. For
-+overlaying a directory called "basedir1", you can just call:
-+
-+ # mini_fo-overlay basedir1
-+
-+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
-+as storage to "/mnt/mini_fo-basedir1/". It has more options though,
-+type "mini_fo-overlay -h" for details.
-+
-+
-+DOCUMENTATION, REPORTING BUGS, GETTING HELP
-+-------------------------------------------
-+
-+Please visit the mini_fo project page at:
-+
-+http://www.denx.de/twiki/bin/view/Know/MiniFOHome
-+
-+
-+WARNINGS
-+--------
-+
-+Never modify the base or the storage directorys while the mini_fo
-+file system is mounted, or you might crash you system. Simply accessing
-+and reading should not cause any trouble.
-+
-+Exporting a mini_fo mount point via NFS has not been tested, and may
-+or may not work.
-+
-+Check the RELEASE_NOTES for details on bugs and features.

-+Release: mini_fo-0.6.1 (v0-6-1)
-+Date: 21.09.2005
-+
-+
-+Changes:
-+--------
-+v0-6-1:
-+
-+- bugfixes (see ChangeLog)
-+
-+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
-+ README for details).
-+
-+v0-6-0:
-+
-+- Support for 2.4 and 2.6 (see Makefile)
-+
-+- Partial hard link support (creating works as expected, but already
-+ existing links in the base file system will be treated as if they
-+ were individual files).
-+
-+- Various bugfixes and cleanups.
-+
-+
-+v0-6-0-pre1:
-+
-+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
-+ many vital mini_fo parts such as the old whiteout list code which
-+ has been replaced by the new META subsystem.
-+
-+- Light weight directory renaming implemented. This means if a
-+ directory is renamed via the mini_fo filesystem this will no longer
-+ result in a complete copy in storage, instead only one empty
-+ directory will be created. All base filed contained in the original
-+ directory stay there until modified.
-+
-+- Special files (creating, renaming, deleting etc.) now working.
-+
-+- Many bugfixes and cleanup, mini_fo is now a lot more stable.
-+
-+
-+v0-5-10:
-+
-+- Final release of the 0-5-* versions. Next will be a complete rewrite
-+ of many features. This release contains several bugfixes related to
-+ directory renaming.
-+
-+
-+v0-5-10-pre6:
-+
-+- Lots of cleanup and several bugfixes related to directory deleting
-+
-+- Directory renaming suddenly works, what is most likely due to the
-+ fact tha that "mv" is smart: if the classic rename doesn't work it
-+ will assume that source and target file are on different fs and will
-+ copy the directory and try to remove the source directory. Until
-+ directory removing wasn't implemented, it would fail to do this and
-+ rollback.
-+ So, directory renaming works for now, but it doesn't yet do what you
-+ would expect from a overlay fs, so use with care.
-+
-+
-+v0-5-10-pre5:
-+
-+- implemented directory deleting
-+- made parsing of mount options more stable
-+- New format of mount options! (See README)
-+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
-+ happily assume it never existed!
-+
-+
-+Implemented features:
-+---------------------
-+
-+- creating hard links (see BUGS on already existing hard links)
-+- lightweight directory renaming
-+- renaming device files, pipes, sockets, etc.
-+- creating, renaming, deleting of special files
-+- deleting directorys
-+- general directory reading (simple "ls" )
-+- creating files in existing directorys
-+- creating directorys
-+- renaming files.
-+- reading and writing files (involves opening)
-+- appending to files (creates copy in storage)
-+- deleting files
-+- llseek works too, what allows editors to work
-+- persistency (a deleted file stay deleted over remounts)
-+- use of symbolic links
-+- creating of device files
-+
-+
-+Not (yet) implemented features:
-+-------------------------------
-+
-+- full hard link support.
-+
-+
-+
-+BUGS:
-+-----
-+
-+Hard links in the base file system will be treated as individual
-+files, not as links to one inode.
-+
-+The main problem with hard links isn't allowing to create them, but
-+their pure existence. If you modify a base hard link, the changes made
-+will only show up on this link, the other link will remain in the
-+original state. I hope to fix this someday. Please note that this does
-+not effect the special hard links '.' and '..', that are handled
-+seperately by the lower fs.

-+ help
-+ Saying Y here includes support for SquashFS 3.0 (a Compressed Read-Only File
-+ System). Squashfs is a highly compressed read-only filesystem for Linux.
-+ It uses zlib compression to compress both files, inodes and directories.
-+ Inodes in the system are very small and all blocks are packed to minimise
-+ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
-+ SquashFS 3.0 supports 64 bit filesystems and files (larger than 4GB), full
-+ uid/gid information, hard links and timestamps.
-+
-+ Squashfs is intended for general read-only filesystem use, for archival
-+ use (i.e. in cases where a .tar.gz file may be used), and in embedded
-+ systems where low overhead is needed. Further information and filesystem tools
-+ are available from http://squashfs.sourceforge.net.
-+
-+ If you want to compile this as a module ( = code which can be
-+ inserted in and removed from the running kernel whenever you want),
-+ say M here and read <file:Documentation/modules.txt>. The module
-+ will be called squashfs. Note that the root file system (the one
-+ containing the directory /) cannot be compiled as a module.

-+ the filesystem. Increasing this amount may mean SquashFS
-+ has to re-read fragments less often from disk, at the expense
-+ of extra system memory. Decreasing this amount will mean
-+ SquashFS uses less memory at the expense of extra reads from disk.
-+
-+ Note there must be at least one cached fragment. Anything
-+ much more than three will probably not make much difference.

-+ Kmalloc memory is the standard kernel allocator, but it can fail
-+ on memory constrained systems. Because of the way Vmalloc works,
-+ Vmalloc can succeed when kmalloc fails. Specifying this option
-+ will make SquashFS always use Vmalloc to allocate the
-+ fragment cache memory.

-+ * - Update patch to 2.4.21
-+ * Sebastian Strollo <sstrollo@nortelnetworks.com>

-+ * Marcel Sebek <sebek64@post.cz>

-+ * After some time of inactivity there is a group taking care
-+ * of IMQ again: http://www.linuximq.net
-+ *
-+ *
-+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7 including
-+ * the following changes:
-+ *
-+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
-+ * - Correction of imq_init_devs() issue that resulted in
-+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
-+ * - Addition of functionality to choose number of IMQ devices
-+ * during kernel config (Andre Correa)
-+ * - Addition of functionality to choose how IMQ hooks on
-+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
-+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
-+ *
-+ *
-+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
-+ * released with almost no problems. 2.6.14-x was released
-+ * with some important changes: nfcache was removed; After
-+ * some weeks of trouble we figured out that some IMQ fields
-+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
-+ * These functions are correctly patched by this new patch version.
-+ *
-+ * Thanks for all who helped to figure out all the problems with

-+ ---help---
-+ Adds a TARPIT target to iptables, which captures and holds
-+ incoming TCP connections using no local per-connection resources.
-+ Connections are accepted, but immediately switched to the persist
-+ state (0 byte window), in which the remote side stops sending data
-+ and asks to continue every 60-240 seconds. Attempts to close the
-+ connection are ignored, forcing the remote side to time out the
-+ connection in 12-24 minutes.
-+
-+ This offers similar functionality to LaBrea
-+ <http://www.hackbusters.net/LaBrea/>, but does not require dedicated
-+ hardware or IPs. Any TCP port that you would normally DROP or REJECT
-+ can instead become a tarpit.

-+
-+2005-10-15 Markus Klotzbuecher <mk@localhost.localdomain>
-+
-+ * Bugfix for a serious memory leak in mini_fo_follow_link.
-+
-+2005-09-21 Markus Klotzbuecher <mk@mary>
-+
-+ * new release 0.6.1
-+
-+ * fix of a compiler warning due to changes in 2.6.13
-+
-+2005-09-21 Klaus Wenninger <klaus.wenninger@siemens.com>
-+
-+ * file.c: readdir: fix for a bug that caused directory entries
-+ to show up twice when using storage filesystems such as
-+ minixfs or pramfs.
-+
-+2005-06-30 Eric Lammerts <eric@lammerts.org>
-+
-+ * fix for an oops when overwriting a binary thats beeing
-+ executed.
-+
-+2005-06-09 <mk@mary>
-+
-+ * Renamed overlay to mini_fo-overlay.
-+
-+ * Added mini_fo-merge script to allow merging of storage and base
-+ after making modifications.
-+
-+2005-05-22 root <mk@mary>
-+
-+ * Added overlay script that allows to easily mount mini_fo ontop
-+ of a given base directory
-+
-+2005-05-10 <mk@mary>
-+
-+ * inode.c: xattr functions return -EOPNOSUPP instead of
-+ -ENOSUPP, what confuses "ls -l"
-+
-+ * Changed license from LGPL to GPL.
-+
-+2005-05-08 root <mk@mary>
-+
-+ * Makefile: clean it up and added make install and make
-+ uninstall.
-+
-+2005-05-06 <mk@mary>
-+
-+ * merged devel branch back to main. [v0-6-0-pre3]
-+
-+ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
-+
-+ * ioctl: removed fist_ioctl stuff, that is not needed for
-+ now.
-+
-+2005-05-03 <mk@mary>
-+
-+ * file.c: simplified mini_fo_open and mini_fo_setattr using
-+ new state changing functions. [devel-0-0-17]
-+
-+ * inode.c: Fixed getattr state bug (see below) in 2.4 function
-+ mini_fo_inode revalidate.
-+
-+ * inode.c: found an other bug in mini_fo_getattr. States are not
-+ reliable in this function, as a file can be opened, unlinked and
-+ the getattr function called. This results in a deleted dentry
-+ with an inode. Fix is to ignore states and simply use the inode
-+ available.
-+
-+2005-04-29 <mk@mary>
-+
-+ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
-+
-+ * file.c: do not use mini_fo_lock so the generic version is
-+ used (I guess).
-+
-+ * inode.c: getattr, never call getattr on lower files, as this
-+ will cause the inum to change.
-+
-+ * inode.c: rename_reg_file renamed to rename_nondir, as it
-+ doesn't matter as long it't not a dir. Removed all
-+ rename_dev_file etc.
-+
-+ * tagged as devel-0-0-15
-+
-+ * inode.c: added support for chosing support for extended
-+ attrs at compile time by XATTR define in mini_fo.h .
-+
-+ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
-+ lower again, what avoids inode number changes that confused
-+ rm again. This is the proper solution.
-+
-+2005-04-24 <mk@mary>
-+
-+ * all files: updated Copyright notive to 2005. [devel-0-0-14]
-+
-+ * inode.c: fixed mini_fo_getattr to not change the inode
-+ number, even if lower files change.
-+
-+ * super.c: fixed a bug that caused deleted base file to show
-+ up suddenly after some time, or after creating a special
-+ file. The problem was that after some time or after special
-+ file creating sync_sb_inodes is called by the vfs, that
-+ called our mini_fo_put_inode. There was (wrongly) called
-+ __meta_put_lists, that nuked the lists, although the inode
-+ was going to continue its life. Moving __meta_put_lists to
-+ mini_fo_clear_inode, where an inode is really destroyed,
-+ solved the problem.
-+
-+
-+2005-04-23 <mk@mary>
-+
-+ * state.c, aux.c: more cleaning up and
-+ simplifications. [devel-0-0-13]
-+
-+ * inode.c: implemented mini_fo_getattr, that was required for
-+ 2.6 because inode_revalidate has been remove there, and the
-+ old "du" bug returned.
-+
-+
-+2005-04-20 <mk@mary>
-+
-+ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
-+ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
-+
-+2005-04-19 <mk@mary>
-+
-+ * Fixed a bug under 2.6 that caused files deleted via mini_fo
-+ not to be deleted properly and therefore the fs filled up
-+ untill no memory was left. [devel-0-0-12]
-+
-+ * Added basic hard link support. This means that creating
-+ hardlinks will work, but existing ones will be treated as
-+ individual files. [devel-0-0-11]
-+
-+2005-04-17 <mk@mary>
-+
-+ * Bugfixes
-+
-+2005-04-13 root <mk@mary>
-+
-+ * Added file state.c for the state transition
-+ functions. Doesn't work very well yet, though...
-+
-+2005-04-12 <mk@mary>
-+
-+ * Porting to 2.6 started, which is easier than expected, also
-+ due to Olivier previous work.
-+
-+2005-04-08 <mk@mary>
-+
-+ * Fixed the bug that caused du to return invalid sizes of
-+ directory trees. The problem was that
-+ mini_fo_inode_revalidate didn't always copy the attributes
-+ from the base inode properly.
-+
-+2005-04-01 Markus Klotzbuecher <mk@chasey>
-+
-+ * Merged devel branch back to main trunk and updated the
-+ RELEASE notes. This will be 0-6-0-pre1.
-+
-+2005-03-31 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed some bugs in rename_reg_file, that only showed up in
-+ the kernel compile test. Kernel compiles cleanly ontop of
-+ mini_fo, now also make mrproper etc. work. Seems pretty stable.
-+
-+2005-03-28 Markus Klotzbuecher <mk@chasey>
-+
-+ * Many, many directory renaming bugfixes and a lot of other
-+ cleanup. Dir renaming seems to work relatively stable.
-+
-+2005-03-22 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing lightweight directory renaming. Some
-+ basic testing indicates it works fine.
-+ Next is to implement testcases for the testsuite and confirm
-+ everything is really working ok.
-+
-+2005-03-18 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing meta.c stuff required for directory
-+ renaming.
-+
-+2005-03-17 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed all compile warnings + an extremly old bug that
-+ somehow crept in while reworking the wol stuff to the META
-+ system. Turning on -Werror again... :-)
-+
-+ * Fixed some bugs in the new rename_reg_file function.
-+
-+ * Rewrote mini_fo rename and split it into several
-+ subfunctions, that handle the different types
-+ seperately. Rewrote the regular file function aswell, as it
-+ was implemented somewhat inefficient.
-+
-+2005-03-16 Markus Klotzbuecher <mk@chasey>
-+
-+ * Implemented new META subsystem, removed old WOL stuff in favor
-+ if it.
-+
-+ * After some basic testing everything seems ok...
-+
-+2005-03-11 Markus Klotzbuecher <mk@chasey>
-+
-+ * Renaming a non regular file caused trouble because I always
-+ tried to copy the contents. Now I only do this for regular
-+ files. mini_fo_rename still isn't implemented properly, renaming
-+ of device files, symlinks etc. results in a empty regular file
-+ instead of the proper type.
-+
-+ * Directory renaming suddenly works! What a surprise! I guess
-+ this is because renaming is implemented as making a copy and
-+ removing the original. Still this might not work
-+ everywhere...
-+
-+2005-03-09 Markus Klotzbuecher <mk@chasey>
-+
-+ * Bugfix, when a mini_fo directory that exists in storage
-+ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
-+ possibly existing WOL file contained in it needs to be
-+ deleted too.
-+
-+ * Starting cleanup: defined state names in order to get rid of
-+ the state numbers.
-+
-+2005-03-08 Markus Klotzbuecher <mk@chasey>
-+
-+ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
-+
-+ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
-+ DEL_REWRITTEN the hash was calculated from the base dentry,
-+ which was wrong and and caused assertions in
-+ __mini_fo_hidden_dentry to fail.
-+
-+2005-02-21 <mk@mary>
-+
-+ * Implemented directory deleting (inode.c)
-+
-+ * main.c: made mini_fo_parse_options a little more robust.
-+
-+2004-12-22 <mk@mary>
-+
-+ * Makefile cleanup and uml stuff, removed unneccessary files
-+
-+ * Created a new and hopefully more informative README
-+
-+ * CHANGELOG: created a new CHANGELOG and added old entries reversely
-+
-+
-+2004-10-24 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Fix: owner and group where not correctly copied from base to
-+ storage.
-+
-+
-+2004-10-05 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of fsync, fasync and lock mini_fo functions.
-+
-+
-+2004-09-29 Bob Lee <bob@pantasys.com>
-+
-+ * Fix of a serious pointer bug
-+
-+
-+2004-09-28 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of mini_fo_mknod and mini_fo_rename, support
-+ for device files.

-+README for the mini_fo overlay file system
-+=========================================
-+
-+
-+WHAT IS MINI_FO?
-+----------------
-+
-+mini_fo is a virtual kernel file system that can make read-only
-+file systems writable. This is done by redirecting modifying operations
-+to a writeable location called "storage directory", and leaving the
-+original data in the "base directory" untouched. When reading, the
-+file system merges the modifed and original data so that only the
-+newest versions will appear. This occurs transparently to the user,
-+who can access the data like on any other read-write file system.
-+
-+Base and storage directories may be located on the same or on
-+different partitions and may be of different file system types. While
-+the storage directory obviously needs to be writable, the base may or
-+may not be writable, what doesn't matter as it will no be modified
-+anyway.
-+
-+
-+WHAT IS GOOD FOR?
-+-----------------
-+
-+The primary purpose of the mini_fo file system is to allow easy
-+software updates to embedded systems, that often store their root
-+file system in a read-only flash file system, but there are many
-+more as for example sandboxing, or for allowing live-cds to
-+permanently store information.
-+
-+
-+BUILDING
-+--------
-+This should be simple. Adjust the Makefile to point to the correct
-+kernel headers you want to build the module for. Then:
-+
-+ # make
-+
-+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
-+kernel.
-+
-+If you are building the module for you current kernel, you can install
-+the module (as root):
-+
-+ # make install
-+
-+or uninstall with
-+
-+ # make uninstall
-+
-+
-+USING THE FILE SYSTEM
-+--------------------
-+
-+the general mount syntax is:
-+
-+ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
-+ <base directory> <mount point>
-+
-+Example:
-+
-+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
-+on it:
-+
-+load the module (as root)
-+
-+ # insmod mini_fo.o for a 2.4 kernel or
-+
-+ # insmod mini_fo.ko for a 2.6 kernel
-+
-+
-+create a storage dir in tmp and a mountpoint for mini_fo:
-+
-+ # mkdir /tmp/sto
-+ # mkdir /mnt/mini_fo
-+
-+and mount the mini_fo file system:
-+
-+ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
-+
-+
-+Now the data stored on the cd can be accessed via the mini_fo
-+mountpoint just like any read-write file system, files can be modified
-+and deleted, new ones can be created and so on. When done unmount the
-+file system:
-+
-+ # unmount /mnt/mini_fo
-+
-+Note that if the file system is mounted again using the same storage
-+file system, of course it will appear in the modified state again. If
-+you remount it using an new empty storage directory, it will be
-+unmodified. Therefore by executing:
-+
-+ # cd /tmp/sto
-+ # rm -rf *
-+
-+you can nuke all the changes you made to the original file system. But
-+ remember NEVER do this while the mini_fo file system is mounted!
-+
-+
-+Alternatively you can use the mini_fo-overlay bash script, that
-+simplifies managing mini_fo mounts. See TOOLS Section.
-+
-+
-+TOOLS
-+-----
-+
-+mini_fo-merge (experimental):
-+
-+This is a bash script that will merge changes contained in the storage
-+directory back to the base directory. This allows mini_fo to function
-+as a cache file system by overlaying a slow (network, ...) file system
-+and using a fast (ramdisk, ...) as storage. When done, changes can be
-+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
-+-h" for details.
-+
-+It can be usefull for merging changes back after a successfull test
-+(patches, software updates...)
-+
-+
-+mini_fo-overlay:
-+
-+This bash script simplifies managing one or more mini_fo mounts. For
-+overlaying a directory called "basedir1", you can just call:
-+
-+ # mini_fo-overlay basedir1
-+
-+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
-+as storage to "/mnt/mini_fo-basedir1/". It has more options though,
-+type "mini_fo-overlay -h" for details.
-+
-+
-+DOCUMENTATION, REPORTING BUGS, GETTING HELP
-+-------------------------------------------
-+
-+Please visit the mini_fo project page at:
-+
-+http://www.denx.de/twiki/bin/view/Know/MiniFOHome
-+
-+
-+WARNINGS
-+--------
-+
-+Never modify the base or the storage directorys while the mini_fo
-+file system is mounted, or you might crash you system. Simply accessing
-+and reading should not cause any trouble.
-+
-+Exporting a mini_fo mount point via NFS has not been tested, and may
-+or may not work.
-+
-+Check the RELEASE_NOTES for details on bugs and features.

-+Release: mini_fo-0.6.1 (v0-6-1)
-+Date: 21.09.2005
-+
-+
-+Changes:
-+--------
-+v0-6-1:
-+
-+- bugfixes (see ChangeLog)
-+
-+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
-+ README for details).
-+
-+v0-6-0:
-+
-+- Support for 2.4 and 2.6 (see Makefile)
-+
-+- Partial hard link support (creating works as expected, but already
-+ existing links in the base file system will be treated as if they
-+ were individual files).
-+
-+- Various bugfixes and cleanups.
-+
-+
-+v0-6-0-pre1:
-+
-+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
-+ many vital mini_fo parts such as the old whiteout list code which
-+ has been replaced by the new META subsystem.
-+
-+- Light weight directory renaming implemented. This means if a
-+ directory is renamed via the mini_fo filesystem this will no longer
-+ result in a complete copy in storage, instead only one empty
-+ directory will be created. All base filed contained in the original
-+ directory stay there until modified.
-+
-+- Special files (creating, renaming, deleting etc.) now working.
-+
-+- Many bugfixes and cleanup, mini_fo is now a lot more stable.
-+
-+
-+v0-5-10:
-+
-+- Final release of the 0-5-* versions. Next will be a complete rewrite
-+ of many features. This release contains several bugfixes related to
-+ directory renaming.
-+
-+
-+v0-5-10-pre6:
-+
-+- Lots of cleanup and several bugfixes related to directory deleting
-+
-+- Directory renaming suddenly works, what is most likely due to the
-+ fact tha that "mv" is smart: if the classic rename doesn't work it
-+ will assume that source and target file are on different fs and will
-+ copy the directory and try to remove the source directory. Until
-+ directory removing wasn't implemented, it would fail to do this and
-+ rollback.
-+ So, directory renaming works for now, but it doesn't yet do what you
-+ would expect from a overlay fs, so use with care.
-+
-+
-+v0-5-10-pre5:
-+
-+- implemented directory deleting
-+- made parsing of mount options more stable
-+- New format of mount options! (See README)
-+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
-+ happily assume it never existed!
-+
-+
-+Implemented features:
-+---------------------
-+
-+- creating hard links (see BUGS on already existing hard links)
-+- lightweight directory renaming
-+- renaming device files, pipes, sockets, etc.
-+- creating, renaming, deleting of special files
-+- deleting directorys
-+- general directory reading (simple "ls" )
-+- creating files in existing directorys
-+- creating directorys
-+- renaming files.
-+- reading and writing files (involves opening)
-+- appending to files (creates copy in storage)
-+- deleting files
-+- llseek works too, what allows editors to work
-+- persistency (a deleted file stay deleted over remounts)
-+- use of symbolic links
-+- creating of device files
-+
-+
-+Not (yet) implemented features:
-+-------------------------------
-+
-+- full hard link support.
-+
-+
-+
-+BUGS:
-+-----
-+
-+Hard links in the base file system will be treated as individual
-+files, not as links to one inode.
-+
-+The main problem with hard links isn't allowing to create them, but
-+their pure existence. If you modify a base hard link, the changes made
-+will only show up on this link, the other link will remain in the
-+original state. I hope to fix this someday. Please note that this does
-+not effect the special hard links '.' and '..', that are handled
-+seperately by the lower fs.

-+
-+Overview
-+--------
-+
-+LinuxPPS provides a programming interface (API) to define into the
-+system several PPS sources.
-+
-+PPS means "pulse per second" and a PPS source is just a device which
-+provides a high precision signal each second so that an application
-+can use it to adjust system clock time.
-+
-+A PPS source can be connected to a serial port (usually to the Data
-+Carrier Detect pin) or to a parallel port (ACK-pin) or to a special
-+CPU's GPIOs (this is the common case in embedded systems) but in each
-+case when a new pulse comes the system must apply to it a timestamp
-+and record it for the userland.
-+
-+Common use is the combination of the NTPD as userland program with a
-+GPS receiver as PPS source to obtain a wallclock-time with
-+sub-millisecond synchronisation to UTC.
-+
-+
-+RFC considerations
-+------------------
-+
-+While implementing a PPS API as RFC 2783 defines and using an embedded
-+CPU GPIO-Pin as physical link to the signal, I encountered a deeper
-+problem:
-+
-+ At startup it needs a file descriptor as argument for the function
-+ time_pps_create().
-+
-+This implies that the source has a /dev/... entry. This assumption is
-+ok for the serial and parallel port, where you can do something
-+useful besides(!) the gathering of timestamps as it is the central
-+task for a PPS-API. But this assumption does not work for a single
-+purpose GPIO line. In this case even basic file-related functionality
-+(like read() and write()) makes no sense at all and should not be a
-+precondition for the use of a PPS-API.
-+
-+The problem can be simply solved if you consider that a PPS source is
-+not always connected with a GPS data source.
-+
-+So your programs should check if the GPS data source (the serial port
-+for instance) is a PPS source too, otherwise they should provide the
-+possibility to open another device as PPS source.
-+
-+In LinuxPPS the PPS sources are simply char devices usually mapped
-+into files /dev/pps0, /dev/pps1, etc..
-+
-+
-+Coding example
-+--------------
-+
-+To register a PPS source into the kernel you should define a struct
-+pps_source_info_s as follow:
-+
-+ static struct pps_source_info_s pps_ktimer_info = {
-+ name : "ktimer",
-+ path : "",
-+ mode : PPS_CAPTUREASSERT | PPS_OFFSETASSERT | \
-+ PPS_ECHOASSERT | \
-+ PPS_CANWAIT | PPS_TSFMT_TSPEC,
-+ echo : pps_ktimer_echo,
-+ owner : THIS_MODULE,
-+ };
-+
-+and then calling the function pps_register_source() in your
-+intialization routine as follow:
-+
-+ source = pps_register_source(&pps_ktimer_info,
-+ PPS_CAPTUREASSERT | PPS_OFFSETASSERT);
-+
-+The pps_register_source() prototype is:
-+
-+ int pps_register_source(struct pps_source_info_s *info, int default_params)
-+
-+where "info" is a pointer to a structure that describes a particular
-+PPS source, "default_params" tells the system what the initial default
-+parameters for the device should be (is obvious that these parameters
-+must be a subset of ones defined into the struct
-+pps_source_info_s which describe the capabilities of the driver).
-+
-+Once you have registered a new PPS source into the system you can
-+signal an assert event (for example in the interrupt handler routine)
-+just using:
-+
-+ pps_event(source, PPS_CAPTUREASSERT, ptr);
-+
-+The same function may also run the defined echo function
-+(pps_ktimer_echo(), passing to it the "ptr" pointer) if the user
-+asked for that... etc..
-+
-+Please see the file drivers/pps/clients/ktimer.c for an example code.
-+
-+
-+SYSFS support
-+-------------
-+
-+If the SYSFS filesystem is enabled in the kernel it provides a new class:
-+
-+ $ ls /sys/class/pps/
-+ pps0/ pps1/ pps2/
-+
-+Every directory is the ID of a PPS sources defined into the system and
-+inside you find several files:
-+
-+ $ ls /sys/class/pps/pps0/
-+ assert clear echo mode name path subsystem@ uevent
-+
-+Inside each "assert" and "clear" file you can find the timestamp and a
-+sequence number:
-+
-+ $ cat /sys/class/pps/pps0/assert
-+ 1170026870.983207967#8
-+
-+Where before the "#" is the timestamp in seconds and after it is the
-+sequence number. Other files are:
-+
-+* echo: reports if the PPS source has an echo function or not;
-+
-+* mode: reports available PPS functioning modes;
-+
-+* name: reports the PPS source's name;
-+
-+* path: reports the PPS source's device path, that is the device the
-+ PPS source is connected to (if it exists).
-+
-+
-+Testing the PPS support
-+-----------------------
-+
-+In order to test the PPS support even without specific hardware you can use
-+the ktimer driver (see the client subsection in the PPS configuration menu)
-+and the userland tools provided into Documentaion/pps/ directory.
-+
-+Once you have enabled the compilation of ktimer just modprobe it (if
-+not statically compiled):
-+
-+ # modprobe ktimer
-+
-+and the run ppstest as follow:
-+
-+ $ ./ppstest /dev/pps0
-+ trying PPS source "/dev/pps1"
-+ found PPS source "/dev/pps1"
-+ ok, found 1 source(s), now start fetching data...
-+ source 0 - assert 1186592699.388832443, sequence: 364 - clear 0.000000000, sequence: 0
-+ source 0 - assert 1186592700.388931295, sequence: 365 - clear 0.000000000, sequence: 0
-+ source 0 - assert 1186592701.389032765, sequence: 366 - clear 0.000000000, sequence: 0
-+
-+Please, note that to compile userland programs you need the file timepps.h
-+(see Documentation/pps/).

-+ PPS (Pulse Per Second) is a special pulse provided by some GPS

-+/* NOTES:
-+ *
-+ * - For now, we won't try to interoperate with a real mmc/sd/sdio
-+ * controller, although some of them do have hardware support for
-+ * SPI protocol. The main reason for such configs would be mmc-ish
-+ * cards like DataFlash, which don't support that "native" protocol.
-+ *
-+ * We don't have a "DataFlash/MMC/SD/SDIO card slot" abstraction to
-+ * switch between driver stacks, and in any case if "native" mode
-+ * is available, it will be faster and hence preferable.
-+ *
-+ * - MMC depends on a different chipselect management policy than the
-+ * SPI interface currently supports for shared bus segments: it needs
-+ * to issue multiple spi_message requests with the chipselect active,
-+ * using the results of one message to decide the next one to issue.
-+ *
-+ * Pending updates to the programming interface, this driver expects
-+ * that it not share the bus with other drivers (precluding conflicts).
-+ *
-+ * - We tell the controller to keep the chipselect active from the
-+ * beginning of an mmc_host_ops.request until the end. So beware
-+ * of SPI controller drivers that mis-handle the cs_change flag!
-+ *
-+ * However, many cards seem OK with chipselect flapping up/down
-+ * during that time ... at least on unshared bus segments.

-[ARM] 4600/1: fix kernel build failure with build-id-supporting binutils
-
-Newer versions of binutils support --build-id, which adds an ELF
-note section called ".note.gnu.build-id" to the output. On the ARM
-kernel build, because there is no explicit mention of this section
-in the shipped ld script, this section is placed at vaddr 0x00000000
-(whereas the normal kernel text/data typically starts at vaddr
-0xc0008000), causing the output of objcopy (Image) to produce a 3G+
-file.
-
-This patch makes objcopy strip the .note.gnu.build-id section from
-the Image file along with all other note sections, which fixes the
-build.

-A similar patch for ppc64 made it upstream with your big ppc64 merge.
-This one is still sitting in http://patchwork.ozlabs.org/linuxppc/
-and didn't make it with the ppc32 equivalent. Thanks.
