  EAV Paging enhances the z/VM Control Program (CP) by
  allowing paging space to be located on Extended Address
  Volumes (EAVs).
  Paging space on ECKD devices can now support cylinders from
  0-1,182,005.
  Volumes must first be formatted, which can be done with the
  new CPFMTXA support, then attached to the system.

  PREREQ: NONE
