[v2,0/7] Implement Most ARMv8.3 Pointer Authentication Features

Message

Aaron Lindsay Feb. 22, 2023, 7:35 p.m. UTC

Changes from v1 of this patchset [0]:

* Changed ISAR feature detection to use '>=' rather than '=='
* Switched around the logic handling EPAC/Pauth2 to play nicely with the
  '>=' ISAR feature detection for EPAC
* Re-organized a stray fragment of a patch to be bisect-friendly
* Moved call-sites for GETPC() to top-level helpers
* Calculate FPAC error code inside syn_pacfail() instead of the
  callsite. 

I have NOT yet made any changes to the properties/documentation (see
"target/arm: Add CPU properties for most v8.3 PAC features") since my
previous patchset - I'm planning to await further discussion about the
appropriate way to organize them before making those changes and
particularly welcome further review there.
