Merge branch 'slab/for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux

Pull SLAB changes from Pekka Enberg:
 "New and noteworthy:

  * More SLAB allocator unification patches from Christoph Lameter and
    others.  This paves the way for slab memcg patches that hopefully
    will land in v3.8.

  * SLAB tracing improvements from Ezequiel Garcia.

  * Kernel tainting upon SLAB corruption from Dave Jones.

  * Miscellanous SLAB allocator bug fixes and improvements from various
    people."
