I am wondering about the merge path for this series (and the `cv` one).
We would like to use it for 7.4 in `drm-rust-next`, but given the
current timing we can either merge it there after `-rc1` is tagged, or
take the bits that apply on `nust-next` now.

The bits that apply being:

- Patch 1 of the `cv!` series [1],
- Patches 1-4 and 6-7 of this series.

(patch 5 touches mostly nova-core and doesn't apply on `rust-next`,
patch 8 lacks the required tags, and patch 9 is a nova-core patch)

Since that's quite a bit of code outside of nova-core, maybe it is
better to merge the non-nova bits mentioned above through the Rust tree
in time for the 7.4 merge window. All the patches I have listed should
have the required tags, but the `cv!` patch needs one last respin to
address the remaining comments and add a "Pitfalls" section at the very
least. Miguel, does that sound doable?
