[PATCH 2/4] drm/ttm: zero allocation only for CPU domain

Thanks for reply, this patch is mainly for performance reason. since TTM is to clear page for all non-fixed memory (GTT and CPU domains), which takes much more CPU overhead. The patch is to remove 'clear page' for GTT domain. btw: Micheal has rejected this patch. Regards, David Zhou (Chunming)
