Merge branch 'akpm' (Andrew's patch-bomb)
Merge misc patches from Andrew Morton:
"Incoming:
- lots of misc stuff
- backlight tree updates

- more checkpoint/restart support
I still have a pile of MM stuff pending - Pekka should be merging
later today after which that is good to go. A number of other things
are twiddling thumbs awaiting maintainer merges."
