Merge branch 'akpm' (Andrew's patch-bomb)

Merge misc patches from Andrew Morton:
 "The MM tree is rather stuck while I wait to find out what the heck is
  happening with sched/numa.  Probably I'll need to route around all the
  code which was added to -next, sigh.

  So this is "everything else", or at least most of it - other small
  bits are still awaiting resolutions of various kinds."
