Log message:
Require NRIP Save support for vmm(4) on AMD hosts.
This feature gives a fast, reliable path to accurately advancing
RIP when emulating certain instructions. Most AMD hardware from the
past 15 years should have NRIP Save and nested paging support so
this drops support for AMD hardware from roughly family 11h and
older with some rare exceptions.
Discussed multiple times in the past.
