Subject: [PATCH 0/6] percpu: Per cpu code simplification fixup
Date: Thu, 17 Jan 2008 14:35:05 -0800 [thread overview]
Message-ID: <20080117223505.203884000@sgi.com> (raw)
This patchset simplifies the code that arches need to maintain to support
per cpu functionality. Most of the code is moved into arch independent
code. Only a minimal set of definitions is kept for each arch.
The patch also unifies the x86 arch so that there is only a single
asm-x86/percpu.h
Based on: 2.6.24-rc8-mm1

fixup:
- rebased from 2.6.24-rc6-mm1 to 2.6.24-rc8-mm1
(removed changes that are in the git-x86.patch)
- added back in missing fold-percpu_modcopy pieces
V3->V4:
- rebased patchset on 2.6.24-rc6-mm1
(removes the percpu_modcopy changes that are already in.)
- change config ARCH_SETS_UP_PER_CPU_AREA to a global var
and use select HAVE_SETUP_PER_CPU_AREA to specify.
V2->V3:
- fix x86_64 non-SMP case
- change SHIFT_PTR to SHIFT_PERCPU_PTR
- fix various percpu_modcopy()'s to reference correct per_cpu_offset()
- s390 has a special way to determine the pointer to a per cpu area
V1->V2:
- Add support for specifying attributes for per cpu declarations (preserves
IA64 model(small) attribute).
- Drop first patch that removes the model(small) attribute for IA64
- Missing #endif in powerpc generic config / Wrong Kconfig
- Follow Randy's suggestions on how to do the Kconfig settings
