-Subject: [PATCH 2/3] Revert "MIPS: Allow ASID size to be determined at boot
- time."
-
-This reverts commit d532f3d26716a39dfd4b88d687bd344fbe77e390.
-
-The original commit has several problems:
-
-1) Doesn't work with 64-bit kernels.
-
-2) Calls TLBMISS_HANDLER_SETUP() before the code is generated.
-
-3) Calls TLBMISS_HANDLER_SETUP() twice in per_cpu_trap_init() when
-   only one call is needed.
-
-[ralf@linux-mips.org: Also revert the bits of the ASID patch which were
-hidden in the KVM merge.]

-Subject: [PATCH 3/3] MIPS: Enable interrupts in arch_cpu_idle()
-
-commit cdbedc61c8 (mips: Use generic idle loop) broke MIPS as I did
-not realize that MIPS wants to invoke the wait instructions with
-interrupts enabled. Don't ask why that works correctly; Ralf suggested
-to get thoroughly drunk before even thinking about it. Looking sober
-at commit c65a5480 ([MIPS] Fix potential latency problem due to
-non-atomic cpu_wait) is not recommended.
-
-Enable interrupts in arch_cpu_idle() on mips to repair the issue.
