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.

Although binutils currently supports use of this flag the details
concerning its effect upon the O32 ABI in userland are still being

be considered experimental and only enabled by those working upon
