So is the plan to remove the other macro from Arm then as well?
Do you mean mfn_to_gfn? If so it does not exist on Arm.
No, I mean the one in context above - set_gpfn_from_mfn().
It is used in common code, so we would need to #idef the caller.
I think it is better to provide a NOP implementation. Could be moved somewhere
in the common header though. Any opinions?
Cheers,
