[PATCH 1/2] drm/ttm: add a way to bo_wait for either the last read or last write

[Marek Olšák]

Hi Thomas,

I have made no progress so far due to lack of time.

Would you mind if I fixed the most important things first, which are:
- sync objects are not ordered, (A)
- every sync object must have its corresponding sync_obj_arg, (B)
and if I fixed (C) some time later.

I planned on moving the two sync objects from ttm into radeon and not
using ttm_bo_wait from radeon (i.e. pretty much reimplementing what it
does), but it looks more complicated to me than I had originally
thought.
