Yep, sounds good.

Can XENMEM_translate_gpfn_list be used to figure where holes in the
physmap (due to ballooning for example) are?  Guess I can "plug" these
holes then by moving around pages using the new source space?
Well, I think it should. I think a hole will return ~0UL as the mfn. That probably deserves an interface macro.
