After review TTM code, i found that when BO is in AGP aperture, the cache
attribute for this BO is often to be "WC".
So user mode page table will be "WC" of course. This guarantee that data
won't be cached by CPU and be visible to GPU correctly.
But how about the opposition in this case? How to guarantee that the CPU see
the correct data which may be cached by GPU?
