      BUFFER EXTENSION structure for PURGE support
      struct buf_ext definition used to PASS purge request
      identification information to the SCSI container.  The
      data from this structure is COPIED by the container.  The
      structure is not directly used nor modified by the
      container.
      The address of EDEVBEXT is passed to the container in the
      SZRBEXT field of each SZREQ request block in a strategy
      call to uniquely identify an I/O request.  A purge request
      is initiated by passing the same address to HCPSZBPU. This
      data is serialized by RDEVAIOR (one active I/O at a time).
      It must be initialized prior to initiating each strategy
      call.
028C  652 Bitstring  128 EDEVBEXT       Start of Buffer Extension
      BUFFER EXTENSION structure for Native Paging PURGE support
      This buf ext is needed to distinguish paging I/O requests
      from normal FBA Emulation requests for purge support.
030C  780 Bitstring  128 EDEVNPBX       Start of Native Paging Buf Ext
      The address overlap list is used by the channel simulator
      to detect chained READ CCWs that use the same data address.
      The length of this table should be greater than or equal
      to the average number of pages processed per READ request.
      Too low a number will cause fragmentation of strategy
      calls resulting in performance degradation.  The
      downside to making it bigger is the overhead of searching
      a longer table as new addresses are added.
