Merge tag 'v3.12' into drm-intel-next

I want to merge in the new Broadwell support as a late hw enabling
pull request. But since the internal branch was based upon our
drm-intel-nightly integration branch I need to resolve all the
oustanding conflicts in drm/i915 with a backmerge to make the 60+
patches apply properly.

We'll propably have some fun because Linus will come up with a
slightly different merge solution.

Conflicts:
	drivers/gpu/drm/i915/i915_dma.c
	drivers/gpu/drm/i915/i915_drv.c
	drivers/gpu/drm/i915/intel_crt.c
	drivers/gpu/drm/i915/intel_ddi.c
	drivers/gpu/drm/i915/intel_display.c
	drivers/gpu/drm/i915/intel_dp.c
	drivers/gpu/drm/i915/intel_drv.h

All rather simple adjacent lines changed or partial backports from
-next to -fixes, with the exception of the thaw code in i915_dma.c.
That one needed a bit of shuffling to restore the intent.

Oh and the massive header file reordering in intel_drv.h is a bit
trouble. But not much.

v2: Also don't forget the fixup for the silent conflict that results
in compile fail ...
