| |
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
Note there are two versions of this patchset: - 2.6.24-rc8-mm1 - 2.6.24-rc8-mm1 + latest (08/1/21) git-x86
Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Mike Travis <travis@sgi.com> --- 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
