Merge tag 'v3.14' into drm-intel-next-queued

Linux 3.14

The vt-d w/a merged late in 3.14-rc needs a bit of fine-tuning, hence
backmerge.

Conflicts:
	drivers/gpu/drm/i915/i915_gem_gtt.c
	drivers/gpu/drm/i915/intel_ddi.c
	drivers/gpu/drm/i915/intel_dp.c

All trivial adjacent lines changed type conflicts, so trivial git
doesn't even show them in the merg commit.
