* 'percpu-cpumask-x86-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (682 commits)
percpu: fix spurious alignment WARN in legacy SMP percpu allocator
percpu: generalize embedding first chunk setup helper
percpu: more flexibility for @dyn_size of pcpu_setup_first_chunk()
percpu: make x86 addr <-> pcpu ptr conversion macros generic
linker script: define __per_cpu_load on all SMP capable archs
x86: UV: remove uv_flush_tlb_others() WARN_ON
percpu: finer grained locking to break deadlock and allow atomic free
percpu: move fully free chunk reclamation into a work
percpu: move chunk area map extension out of area allocation
percpu: replace pcpu_realloc() with pcpu_mem_alloc() and pcpu_mem_free()
x86, percpu: setup reserved percpu area for x86_64
percpu, module: implement reserved allocation and use it for module percpu variables
percpu: add an indirection ptr for chunk page map access
x86: make embedding percpu allocator return excessive free space
percpu: use negative for auto for pcpu_setup_first_chunk() arguments
percpu: improve first chunk initial area map handling
percpu: cosmetic renames in pcpu_setup_first_chunk()
percpu: clean up percpu constants
