Subject: [ 49/57] drm/radeon: avoid UVD corruption on AGP cards using GPU gart

3.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@....com>

commit 4ca5a6cba53e13b8fd153b0762b4128fab6a3cfb upstream.

If the user has forced the driver to use the internal GPU gart
rather than AGP on an AGP card, force the buffers to vram
as well.
