Chris Wilson aaed9e9722 sna: Encourage promotion of snooped CPU bo to real GPU bo 
This fixes the regression in performance of fishietank on gen2. As
the texture atlas is too large to be tiled, one might presume that it
has the same performance characteristics as the snooped linear CPU
buffer. It does not. Therefore if we attempt to reuse a vmap bo, promote
it to a full GPU bo. This hopefully gains the benefit of avoiding the
copy for single shot sources, but still gives us the benefit of avoiding
the clflushes.

On the plus side, it does prove that gen2 handles snoopable memory from
both the blitter and the sampler!

What is xf86-video-intel
------------------------
The xf86-video-intel module is an open-source 2D graphics driver for
the X Window System as implemented by X.org. It supports a variety of
Intel graphics chipsets including:

	i810/i810e/i810-dc100,i815,
	i830M,845G,852GM,855GM,865G,
	915G/GM,945G/GM/GME,946GZ
	G/GM/GME/Q965,
	G/Q33,G/Q35,G41,G/Q43,G/GM/Q45
	PineView-M (Atom N400 series)
	PineView-D (Atom D400/D500 series)

Where to get more information about the driver
