Tested-by: Eric Anholt <[email protected]> Tested on my 865G using openarena 5 times before and after, and x11perf -aa24text 2 times before and after, with no stability or performance change (and yes, it was stable). I was concerned I wasn't getting good enough coverage of the chipset flush path, so I also hacked the 2D driver to upload the batch using bo_map; memcpy; bo_unmap instead of bo_subdata, with no change. before was ac66808814036b4c33dd98091b2176ae6157f1a8. after was the cherry-pick on top of that.
