I wouldn't welcome this - instead, the maximum range of
memory ever expected to be added should be controlled by a
command line option for that purpose. And even without such,
instead of completely avoiding the adjustment, it should be
done assuming the maximum amount a 32-bit domain would
ever get to see (128Gb), which would still make the hole
smaller than it is on a 32-bit hv.
