Merge tag 'v3.14-rc6' into drm-intel-next-queued
Linux 3.14-rc6 I need the hdmi/dvi-dual link fixes in 3.14 to avoid ugly conflicts when merging Ville's new hdmi cloning support into my -next tree Conflicts: drivers/gpu/drm/i915/Makefile drivers/gpu/drm/i915/intel_dp.c Makefile cleanup conflicts with an acpi build fix, intel_dp.c is trivial.
