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.
