This series, based on kvmtool master [1], implements basic support for
pointer authentication and SVE for guests.  This superseded the
previous v3 series [2].

A git tree is also available [3].

For pointer auth, I include Amit's v10 patch [4], 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 so that that can be folded together as appropriate.]


This series has been tested against Linux v5.2-rc1.

After discussion with Will, the command-line options for controlling
pointer auth and SVE support have all been dropped, since they are not
useful to normal users: instead, we just default to the best
configuration that the host supports.  There's always the option to add
this functionality back in some more appropriate form later, if someone
has a use for it.

See the individual patches for other minor changes.
