Merge branch 'akpm' (incoming from Andrew)
Merge misc patches from Andrew Morton:
- Florian has vanished so I appear to have become fbdev maintainer

- Joel and Mark are distracted to welcome to the new OCFS2 maintainer
- The backlight queue
- Small core kernel changes
- lib/ updates
- The rtc queue
- Various random bits
