I split out the series into a few parts including about a dozen which were merged in the last window, but this brings a bunch of them together again for proposed merge. Since last posting, this is rebased with some patches merged. Some patches have also been deferred. No major changes to code, changelogs have been improved including some numbers and better explanation for HPT guest performance regression. This has been tested with radix host and hash / radix guest and hash host / hash guest on P9. Also hash guest and PR KVM hash guest, and a PR KVM nested hash guest, and radix guest and nested HV KVM radix nested guest. P8 with SMT guest. Also P10 with radix and hash guests. It has been tested with RHEL6,7,8,9 and AIX guests.
