Conversion to the reservation api is next on the list, after
that the functionality can be restored with rcu.

This will ensure we always hold the required lock when calling those functions.

Apart from some code inside ttm itself and nouveau_bo_vma_del,
this is the only place where ttm_bo_wait is used without a reservation.
Fix this so we can remove the fence_lock later on.

After the switch to rcu the reservation lock will be
removed again.

This allows us to more fine grained specify where to place the buffer object.

Reported by Coverity.  The intention is that the return value is
checked, but let's be more paranoid and make it extremely obvious
if something forgets to.

We have another version of it implemented in SW, however, that version
isn't serialised with normal PGRAPH operation and can possibly clobber
the enables for another context.

This is the same method that's implemented by the NVIDIA binary driver.

GF117 has smaller buffer allocated, as per register setup.

Default ZBC table is compatible with binary driver defaults.

Userspace will need to be updated to take full advantage of this
feature, however, some applications will see a performance boost
without updated drivers.
