drm/ttm: fix caching problem on non-PAT systems.
http://bugzilla.kernel.org/show_bug.cgi?id=15328 This fixes a serious regression on AGP/non-PAT systems, where pages were ending up in the wrong state and slowing down the whole system. [airlied: taken this from the bug as the other option is to revert the change which caused it]. Tested-by: John W. Linville (in bug). Signed-off-by: Dave Airlie <airlied@redhat.com>
