Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

Pull DRM update from Dave Airlie:
 "This is a bit larger due to me not bothering to do anything since
  before Xmas, and other people working too hard after I had clearly
  given up.

  It's got the 3 main x86 driver fixes pulls, and a bunch of tegra
  fixes, doesn't fix the Ironlake bug yet, but that does seem to be
  getting closer.

   - radeon: gpu reset fixes and userspace packet support
   - i915: watermark fixes, workarounds, i830/845 fix,
   - nouveau: nvd9/kepler microcode fixes, accel is now enabled and
     working, gk106 support
   - tegra: misc fixes."
