I've already talked with Christoph that we probably want to switch TTM

OK, would that mean us ditching other memory modes completely? And
on-the-fly caching transitions? or is it just for the special case of
cached coherent memory? Do we need to cache the coherent kernel
mappings in TTM as well, for ttm_bo_kmap()?
Reading this again, I wanted to point out that I'm not against this.
Just curious.
