As hpa noted recently in another thread [0] that is precisely what
hardware_subarch and hardware_subarch_data was meant to be used for,
and its what I'm alluding to.
The only thing though is that as far as we're concerned on x86 we had
expected use of hardware_subarch and hardware_subarch_data only for
PV, and not for HVM. This seems to be HVM related, but I think this is
just a rebranding of PVH to HVMLite, right, so I think the use case of
hardware_subarch and hardware_subarch_data are still welcomed as
expected in the original design.
