Merge remote-tracking branch 'airlied/drm-core-next' into drm-intel-next-queued
Backmerge of drm-next to resolve a few ugly conflicts and to get a few fixes from 3.4-rc6 (which drm-next has already merged). Note that this merge also restricts the stencil cache lra evict policy workaround to snb (as it should) - I had to frob the code anyway because the CM0_MASK_SHIFT define died in the masked bit cleanups. We need the backmerge to get Paulo Zanoni's infoframe regression fix for gm45 - further bugfixes from him touch the same area and would needlessly conflict. Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
