[GIT PULL] percpu fixes for 3.4-rc6

[Tejun Heo]

Hello, Linus.

This pull request contains two patches.  One is kmemleak annotation
fix which isn't critical.  The other is kinda serious.  Depending on
NUMA topology, percpu allocator may end up assigning overlapping
regions for the static percpu areas for different CPUs.  While
critical, the bug has been there for a very long time and only few
configurations seem to be affected (NUMA configurations w/ no memory
nodes for example) - so, while it's critical, it isn't exactly urgent.

If there isn't gonna be another rcX, I think it would be better to
pull the fix as part of the next merge window and backport through
-stable.

So, depending on release schedule, please consider pulling from the
following branch.

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu.git for-3.4-fixes
