They don't quite fit with the other PV calls in there which use a
different HV calling mechanism alltogether, but I can certainly add a
specific section.

As to adding things to PAPR, let's assume for now that this isn't
possible :-) Besides, those two hypercalls are pretty specific to the
way things are implemented in qemu and are in both case more or less
private mechanisms used to communicate between qemu and the SLOF
firmware we run in inside qemu, they aren't really used by random guest
SW and aren't meant to be.

It's a bit like if you had private calls between seabios and qemu...

Cheers,
Ben.
