[Andrew Morton <akpm@linux-foundation.org>]

- A few misc subsystems

- There is a lot of MM material in Willy's tree.  Folio work and
  non-folio patches which depended on that work.

  Here I send almost all the MM patches which precede the patches in
  Willy's tree.  The remaining ~100 MM patches are staged on Willy's
  tree and I'll send those along once Willy is merged up.

  I tried this batch against your current tree (as of
  51912904076680281) and a couple need some extra persuasion to apply,
  but all looks OK otherwise.
