* Avocado tests for ppc64 to boot FreeBSD, run guests with emulated
  or nested hypervisor facilities, among other things.
* Update ppc64 CPU defaults to Power10.
* Add a new powernv10-rainier machine to better capture differences
  between the different Power10 systems.
* Implement more device models for powernv.
* 4xx TLB flushing performance and correctness improvements.
* Correct gdb implementation to access some important SPRs.
* Misc cleanups and bug fixes.
