Merge branch 'slab/next' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg...

Pull SLAB changes from Pekka Enberg:
 "Most of the changes included are from Christoph Lameter's "common
  slab" patch series that unifies common parts of SLUB, SLAB, and SLOB
  allocators.  The unification is needed for Glauber Costa's "kmem
  memcg" work that will hopefully appear for v3.7.

  The rest of the changes are fixes and speedups by various people."
