Subject: [GIT PULL] percpu for v2.6.35-rc1

Hello, Linus.

Please pull from the following branch to receive percpu changes for
2.6.35-rc1.

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu.git for-linus

There are six commits.  One is to add sparse annotation to ia64.  All
the others are to implement nommu percpu support.  blackfin does SMP
w/o mmu and thus requires percpu allocator which doesn't make use of
remapping in the vmalloc area.  Percpu chunk [de]allocation and
[de]population code paths are factored out and nommu simply allocates
contiguous kernel memory for each unit.

Thanks.

Tejun Heo (6):
      percpu: factor out pcpu_addr_in_first/reserved_chunk() and update per_cpu_ptr_to_phys()
      percpu: reorganize chunk creation and destruction
      percpu: misc preparations for nommu support
      percpu: move vmalloc based chunk management into percpu-vm.c
      percpu: implement kernel memory based chunk allocation
      ia64: add sparse annotation to __ia64_per_cpu_var()
