* '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
  x86: un-__init fill_pud/pmd/pte
  x86: remove vestigial fix_ioremap prototypes
