Merge branch 'akpm' (patches from Andrew Morton)
Merge fixes from Andrew Morton:
"The nmi patch and watchdog patch aren't actually fixes - they're
features which needed a few last-minutes touchups.
Otherwise, a rather large batch of fixes - ocfs2 review takes a while
and I got distracted and missed last week's batch"
