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.
