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."
