Pull drm fix from Dave Airlie:
 "This fixes the mmap regression reported to me on irc by an i686 kernel
  user today, he's tested the fix works, and I've audited all the drm
  drivers for the bad mmap usage and since we use the mmap offset as a
  lookup in a table we aren't inclined to have anything bad in there"

[ See commit dc821e60f3fd ("mmap: introduce sane default mmap limits")
  for details and the note on why the GPU drivers were expected to be a
  special case.    - Linus ]
