  Raise MAXDSIZ from 8G to 32G.  The old limit was just an arbitary choice
  that was greater than 4G.  I originally used the same values as i386 in
  order to save opening a new PML4 page slot, but in the day of gigabytes
  of memory, worrying about a 4K page seems futile.  Moving from 8 to 32G
  moves the page to a different index, it doesn't increase the number of
  pages used.
