2.6.35-stable review patch. If anyone has any objections, please let us know. ------------------ From: Alex Deucher <alexdeucher@xxxxxxxxx> Not upstream in Linus's tree as it was fixed by a much more intrusive patch in a different manner, commit c919b371cb734f42b11 2.6.35 and 2.6.36 do not contain blit support for evergreen asics so if they use unmappable vram, you can end up with an unreachable buffer address. This should not be applied to drm-next as that tree already contains evergreen blit support. This should only be applied to the 2.6.35 and 2.6.36 stable trees.
