Merge branch 'akpm' (incoming from Andrew)

Merge misc patches from Andrew Morton:

 - Florian has vanished so I appear to have become fbdev maintainer
   again :(

 - 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
