When the guest (firmware specifically) knows how big
the address space actually is it can be used better.
Some more background:
https://bugzilla.redhat.com/show_bug.cgi?id=2084533
This is a RfC series exposes the information via cpuid.
v2:
- change fvm hint name.
- better commit message.
take care,
Gerd
