The only flaw in this is if KVM gets handed a CPUID model that enumerates support for 2025 (or whenever the next update comes) but not 2022. Hmm, though if Microsoft defines each new "version" as a full superset, then even that theoretical bug goes away. I'm happy to be optimistic for once and give this a shot. I definitely like that it makes it easier to see the deltas between versions.
Okay, I have queued the series but I still haven't gone through all the comments. So this will _not_ be in the 5.21 pull request.
The first patch also needs a bit more thought to figure out the impact on userspace and whether we can consider syndbg niche enough to not care.
