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

Pull SLAB changes from Pekka Enberg:
 "This contains preparational work from Christoph Lameter and Glauber
  Costa for SLAB memcg and cleanups and improvements from Ezequiel
  Garcia and Joonsoo Kim.

  Please note that the SLOB cleanup commit from Arnd Bergmann already
  appears in your tree but I had also merged it myself which is why it
  shows up in the shortlog."
