[GIT PULL] percpu changes for 2.6.34-rc1

[Tejun Heo]

Hello, Linus.

Please pull from the following percpu branch.

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

The branch contains the following changes.

* Remove per_cpu__ prefix from static per-cpu variables and access the
  static and dynamic percpu variables the same way.  This allows
  handling and manipulating percpu addresses just like any other
  addresses.

* Implement __percpu sparse annotation which marks percpu addresses to
  belong to a different address space.  This replaces the per_cpu__
  prefix which used to protect illegal accesses to static percpu
  variables and also extends the protection such that it covers both
  static and dynamic percpu variables and any pointer which deals with
  percpu addresses.

* Add __percpu annotations to several subsystems.  Others are being
  routed through respective subsystem trees.

* Christoph Lameter's this_cpu_*() conversion series on allocator
  related stuff and local_t users.  Good part of local_t has been
  replaced with this_cpu_*() but the conversion isn't complete yet.
  The last remaining user is ringbuffer and it isn't clear whether
  it'll be possible to replace it completely with percpu variables.

* Now unused part of local_t has been removed.

* WANG Cong's pcpu_[de]populate_chunk() refactor patch.

Merging into 13dda80e48439b446d0bc9bab34b91484bc8f533 doesn't cause
any conflict.

Thanks.
