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

- a small number of updates to scripts/, ocfs2 and fs/buffer.c

- most of MM.  I still have quite a lot of material (mostly not MM)
  staged after linux-next due to -next dependencies.  I'll send thos
  across next week as the preprequisites get merged up.
