I've touched the resource/object id handling too, see my "drm/virtio:
rework ttm resource handling" patch series
(https://patchwork.freedesktop.org/series/50382/).  Which still needs a
review btw.

I think that series obsoletes patch 3/4 (object id fixes) of your
series.  The other patches should rebase without too much trouble, you
could do that as well when preparing v2 ...

cheers,
