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-rc6-mm1 --- 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 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 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.
