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
