Looks like we are going to need to full series (or at least until and
including patch 11) before this can get in. Gary, what tree are you
planning to merge the register projection series into? It would be nice
if we could do it in a way that makes it possible for this series to be
merged shortly after (either through `drm-rust-next`, or a merged signed
tag) for the next cycle.
