This tidies up things, and fixes a few corner cases and unfinished
"XXX:" bits. The major one being "bad host interrupt" detection and
handling (taking a MCE/SRESET while switching into guest regs) which
was missing previously from the new P9 path.
Adds a few new patches and makes some changes for issues noticed
by reviewers (thank you).
Thanks,
Nick
