Merge tag 'v3.10-rc2' into drm-intel-next-queued
Backmerge Linux 3.10-rc2 since the various (rather trivial) conflicts grew a bit out of hand. intel_dp.c has the only real functional conflict since the logic changed while dev_priv->edp.bpp was moved around. Also squash in a whitespace fixup from Ben Widawsky for i915_gem_gtt.c, git seems to do something pretty strange in there (which I don't fully understand tbh). Conflicts: drivers/gpu/drm/i915/i915_reg.h drivers/gpu/drm/i915/intel_dp.c Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
