Gerd rebased his series on top of this, so review would be neat to unblock
everything. I'd like to get this all landed for 5.4.

Just pinged Gerd on this, so we can start coordination.
btw planning to review this from amd side, I'd like to ditch
gem_prime_res_obj especially with Gerd series it's pointless.

Not entirely, they still remove the gem_prime_res_obj. Setting up
gem_bo.resv is only one half of what these do here. And yeah I think that
single addition can be removed again when Gerd's stuff lands.

I think r-b from Thomas Zimmermann (or some other ttm+gem stakeholder) and
we're good to land them. Thomas Hellstrom mellowed down his "nack" to
"I'll look at this in August again and course-correct if necessary".

Those patches would become superfluous when merging Gerd's work.
But I'm not sure if that is going to fly soon or not.

[PATCH 4/7] drm/radeon: Fill out gem_object->resv
That way we can ditch our gem_prime_res_obj implementation. Since ttm
absolutely needs the right reservation object all the boilerplate is
already there and we just have to wire it up correctly.
Note that gem/prime doesn't care when we do this, as long as we do it
before the bo is registered and someone can call the handle2fd ioctl
on it.
Aside: ttm_buffer_object.ttm_resv could probably be ditched in favour
of always passing a non-NULL resv to ttm_bo_init(). At least for gem
drivers that would avoid having two of these, on in ttm_buffer_object
and the other in drm_gem_object, one just there for confusion.
