[Intel-gfx] [PATCH] drm/i915: Introduce vblank work function

Ok thanks. 

To add weight to it becoming official in some form, we're using it for various deferred operations:
	drm/i915: Make plane switching asynchronous
	drm/i915: Asynchronously unpin the old framebuffer after the next vblank	

They aren't my patches but I believe they should be upstreamed in the near future. The claim is that these give a noticeable performance boost.

I'll leave it in and hope it becomes official.
