			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 ... Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
