- Separate out __get_cpu_var accesses of cpumasks and create a special patch that handles the configuration dependent conversion to either this_cpu_read() or this_cpu_ptr(). If this is problematic
then the last 2 patches of the series can be dropped top leave __get_cpu_var use for these cases intact.
- Rebase against 3.17-rc1
- Convert newly introduced uses of __get_cpu_var
- Use Feng's korg testing to validate patch in a series of configurations

Cover letter [PATCH 00/35] percpu: Consistent per cpu operations V7
V6->V7
- Separate out __get_cpu_var accesses of cpumasks and create a special patch that handles the configuration dependent conversion to either this_cpu_read() or this_cpu_ptr(). If this is problematic
then the last 2 patches of the series can be dropped top leave __get_cpu_var use for these cases intact.
- Rebase against 3.17-rc1
- Convert newly introduced uses of __get_cpu_var
- Use Feng's korg testing to validate patch in a series of configurations
- Remove portions of the overview that describe patches already merged.

V4->V5
- Remove patches that were merged
- Update patches against 3.16-rc1
- randconfig debugging on x86
- All patches can be merged individually now (asid from the last two that remove functions)
- Non x86 and powerpc architecture patches have minimal verification.
V3->V4:
- Rediff patches
- Put the patches first that define the new API.
- Add patches to convert the __get_cpu_var stuff added in 3.14
V2->V3:
- Rediff patches
- Fix breakage caused by mips patches. Add a mips patch to convert from local_t.
- Update some descriptions.
V1->V2:
- Move legacy definition for __this_cpu_ptr into include/asm-generic/percpu.h so that users bypassing include/linux/percpu.h do not break (affects tile and s390)
- Merge raw_cpu_ops core and the patch to rename x86 __this_cpu primitives into one. Otherwise breakage will occur since x86 __this_cpu ops will fall back to generic ops which is not tolerated well by the preempt hackery in x86.
- Add notes to each patch that depends on another to avoid mismerges. Add acks etc.
- Use quilt-0.61 with the bug fix that ensures all mailing lists receive the postings intended for them.
The patches are follow on patches that complete the conversion of __get_cpu_var uses. Aside from the 4 last patches all of them can be applied independently. The last 4 patches deal with removal of macros that are no longer needed because the earlier patches converted the usage.
