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.
