Subject: [PATCHSET linux-2.6-x86:core/percpu] x86: misc clean up and unify x86_32/64 code paths
Date: Wed, 21 Jan 2009 17:46:08 +0900 [thread overview]
Message-ID: <1232527578-1960-1-git-send-email-tj@kernel.org> (raw)
Hello,
This patchset contains the following 10 patches mostly unifying 32 and
64bit code paths. 0001 and 0007-0010 are from me and 0002-0006 are
from Brian Gerst.
0001-x86-update-canary-handling-during-switch.patch
0002-x86-clean-up-gdt_page-definition.patch
0003-x86-fix-percpu_write-with-64-bit-constants.patch
0004-x86-set-fs-to-__KERNEL_PERCPU-unconditionally-for.patch
0005-x86-merge-mmu_context.h.patch
0006-x86-merge-irq_regs.h.patch
0007-x86-uv-cleanup.patch
0008-x86-prepare-for-tlb-merge.patch
0009-x86-make-x86_32-use-tlb_64.c.patch
0010-x86-rename-tlb_64.c-to-tlb.c.patch
0001-0002 clean up after previous percpu changes. 0003 improves
percpu op slightly. 0004 simplifies x86_32 init path. 0005-0010
unifies mmu_context.h, irq_regs.h and tlb.c, which not only simplifies
the source code but also improves performance by applying
optimizations implemented for either bitness to the other one while
unifying.
The following git tree contains the above changes on top of
core/percpu[1]. Please pull from it if there's no objection.
