* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
percpu: add __percpu sparse annotations to what's left
percpu: add __percpu sparse annotations to fs
percpu: add __percpu sparse annotations to core kernel subsystems
local_t: Remove leftover local.h
this_cpu: Remove pageset_notifier
this_cpu: Page allocator conversion
percpu, x86: Generic inc / dec percpu instructions
local_t: Move local.h include to ringbuffer.c and ring_buffer_benchmark.c
module: Use this_cpu_xx to dynamically allocate counters
local_t: Remove cpu_local_xx macros
percpu: refactor the code in pcpu_[de]populate_chunk()
percpu: remove compile warnings caused by __verify_pcpu_ptr()
percpu: make accessors check for percpu pointer in sparse
percpu: add __percpu for sparse.
percpu: make access macros universal
percpu: remove per_cpu__ prefix.
