Merge branch 'akpm' (patches from Andrew)

Merge misc fixes from Andrew Morton:
 "The usual shower of hotfixes.

  Chris's memcg patches aren't actually fixes - they're mature but a few
  niggling review issues were late to arrive.

  The ocfs2 fixes are quite old - those took some time to get reviewer
  attention.

  Subsystems affected by this patch series: ocfs2, hotfixes, mm/memcg,
  mm/slab-generic"
