Merge branch 'master' into modesetting-101 - TTM & typedef removal
Conflicts: linux-core/drmP.h linux-core/drm_bo.c linux-core/drm_drv.c linux-core/drm_objects.h shared-core/drm.h shared-core/i915_dma.c shared-core/i915_drv.h shared-core/i915_irq.c Mostly removing typedefs that snuck into the modesetting code and updating to the latest TTM APIs. As of today, the i915 driver builds, but there are likely to be problems, so debugging and bugfixes will come next.
