Merge branch 'akpm' (patches from Andrew)

Merge fifth set of updates from Andrew Morton:

 - A few things which were awaiting merges from linux-next:
     - rtc
     - ocfs2
     - misc others

 - Willy's "dax" feature: direct fs access to memory (mainly NV-DIMMs)
   which isn't backed by pageframes.
