I thought zholes stuff freed the struct pages. Maybe that was done
by hand.

Not sure, ISTR something about this going on but I don't see any extant
examples. At any rate, it should be easy to do it by hand, just make
sure there are struct pages tracking the holes in mem_map and free the
space in mem_map that would track the holes.
