Merge branch 'master' into vblank-rework, fixup remaining drivers

Conflicts:

	linux-core/drmP.h
	linux-core/drm_drv.c
	linux-core/drm_irq.c
	shared-core/i915_drv.h
	shared-core/i915_irq.c
	shared-core/mga_drv.h
	shared-core/mga_irq.c
	shared-core/radeon_drv.h
	shared-core/radeon_irq.c

Merge in the latest master bits and update the remaining drivers (except
mach64 which math_b is working on).  Also remove the 9xx hack from the i915
driver; it seems to be correct.
