Pull drm fixes from Dave Airlie:
 "I realise this a bit bigger than I would want at this point.

  Exynos is a large chunk, I got them to half what they wanted already,
  and hey its ARM based, so not going to hurt many people.

  Radeon has only two fixes, but the PLL fixes were a bit bigger, but
  required for a lot of scenarios, the fence fix is really urgent.

  vmwgfx: I've pulled in a dumb ioctl support patch that I was going to
  shove in later and cc stable, but we need it asap, its mainly to stop
  mesa growing a really ugly dependency in userspace to run stuff on
  vmware, and if I don't stick it in the kernel now, everyone will have
  to ship ugly userspace libs to workaround it.

  nouveau: single urgent fix found in F18 testing, causes X to not start
  properly when f18 plymouth is used

  i915: smattering of fixes and debug quieting

  gma500: single regression fix

  So as I said a bit large, but its fairly well scattered and its all
  stuff I'll be shipping in F18's 3.6 kernel."
