The behaviour of the Address Translation Mode on Interrupt resource is
not consistently supported by all CPU versions or all KVM versions. In
particular KVM HV only supports mode 0 on POWER7 processors and some
early POWER9 processors, and does not support mode 2 anywhere. KVM PR
only supports mode

If we do, we should probably change the
default value for this cap based on cpu model in
default_caps_with_cpu().
We allegedly still support POWER7 KVM in Linux. I've never tested it
and I don't know how much it's used at all. Probably should keep it
working here if possible. I'll look into defa
