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." * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (34 commits) Revert "drm: tegra: protect DC register access with mutex" drm: tegra: program only one window during modeset drm: tegra: clean out old gem prototypes drm: tegra: remove redundant tegra2_tmds_config entry drm: tegra: protect DC register access with mutex drm: tegra: don't leave clients host1x member uninitialized drm: tegra: fix front_porch <-> back_porch mixup drm/nve0/graph: fix fuc, and enable acceleration on all known chipsets drm/nvc0/graph: fix fuc, and enable acceleration on GF119 drm/nouveau/bios: cache ramcfg strap on later chipsets drm/nouveau/mxm: silence output if no bios data drm/nouveau/bios: parse/display extra version component drm/nouveau/bios: implement opcode 0xa9 drm/nouveau/bios: update gpio parsing apis to match current design drm/nouveau: initial support for GK106 drm/radeon: add WAIT_UNTIL to evergreen VM safe reg list drm/i915: disable shrinker lock stealing for create_mmap_offset drm/i915: optionally disable shrinker lock stealing drm/i915: fix flags in dma buf exporting drm/radeon: add support for MEM_WRITE packet ...
