Pull drm fixes from Dave Airlie: "This is just a regular fixes pull apart from the qxl one, it has radeon and intel bits in it, The intel fixes are for a regression with the RC6 fix and a 3.10 hdmi regression, whereas radeon is more DPM fixes, a few lockup fixes and some rn50/r100 DAC fixes" * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: drm/radeon/dpm: fix r600_enable_sclk_control() drm/radeon/dpm: implement force performance levels for rv6xx drm/radeon/dpm: fix displaygap programming on rv6xx drm/radeon/dpm: fix a typo in the rv6xx mclk setup drm/i915: initialize gt_lock early with other spin locks drm/i915: fix hdmi portclock limits drm/radeon: fix combios tables on older cards drm/radeon: improve dac adjust heuristics for legacy pdac drm/radeon: Another card with wrong primary dac adj drm/radeon: fix endian issues with DP handling (v3) drm/radeon/vm: only align the pt base to 32k drm/radeon: wait for 3D idle before using CP DMA
