This reverts commit d180de35320eafa3df3d76f0e82b332656530126.
This is a radeon specific hack that causes problems on nouveau
when combined with the SHARED flag later. If radeonsi needs a fix
for this, please fix it in the driver.
Actually it isn't radeon specific. Using linear surfaces for this makes
sense because tilling isn't beneficial and the surfaces can potentially
be shared with other GPUs using the VDPAU OpenGL interop.
The problem is that I actually can't say if a surfaces will be shared
with another GPU or not when it is created. So the driver needs to be
able to handle this case gracefully and move the surface to GART on
demand when it is opened by another GPU.

I don't think we have actually tested this with PRIME and I'm pretty
sure there are some loose ends which still needs to be fixed for radeon
as well.
So the patch is Acked-by: Christian König <christian.koe...@amd.com> for
now, but essentially we need to find a better solution to this.

Christian.
