This superseded the previous v3 series [2].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.
