This series, based on kvmtool master [1], implements basic support for
pointer authentication and SVE for guests.
A git tree is also available [2].
For pointer auth, I include Amit's v10 patch [3], with some additional
refactoring to sit nicely alongside SVE, and some cosmetic / diagnostic
tidyups discussed during review on-list. (I've kept the extra changes
separate for easier review, but they could be folded if desired.)
[Maintainer note: I'd like Amit to comment on my changes on top of his
pointer auth patch, but the first 4 patches just re-sync headers and
could be pulled earlier if you feel like it.]
This series has been tested against Linux v5.2-rc1.
If people have a strong view on the --sve-vls parameter, I'd be
interested to discuss what that should look like. Since this is
primarily a debug/experimentation option, the current implementation is
probably good enough though.
