    Subject[PATCH 0/7] percpu: Per cpu code simplification rc8-mm1-fixup with git-x86

    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

    Based on 2.6.24-rc8-mm1 + latest (08/1/21) git-x86

    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 <>
    Signed-off-by: Mike Travis <>


    - 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

    - 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.

    - fix x86_64 non-SMP case
    - 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

    - 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
