  12          This is the Linux Xen port.  Enabling this will allow the
  13          kernel to boot in a paravirtualized environment under the
  14          Xen hypervisor.

  22         The pseudo-physical to machine address array is sized
  23         according to the maximum possible memory size of a Xen
  24         domain.  This array uses 1 page per gigabyte, so there's no
  25         need to be too stingy here.

  37          Enable statistics output and various tuning options in debugfs.
