 NAME       : HCPQSBLK
 DESCRIPTION: (QSBLK) QDIO Statistics Block
 DSECT      : QSBLK
 FUNCTION   : Control Block used to maintain various counters for
              QDIO connections.
 CREATED BY : Dynamically created when a guest issues
              an Establish-QDIO-Queues CCW.
 DELETED BY : Deleted by HCPRELST when a QDIO Activate-
              QDIO-Queues channel command terminates.
 ANCHORED   - QDIO Block for the VDEV in QDIQSBLK.
 General comm nts  -  All fields are serialized using
              Compare and Swap.

      The number of times CP Millicode could not unpin a page
      because an access exception condition exists that is a
      higher priority than an addressing exception for fetching
      the PTE for the designated page.
0058   88 Signed       4 QSBUPF64       Page UnPin Failure 1
      PEI Code (65) Page UnPin Failure 2              (QSBUP65)

      because the PGSTE page-control-interlock PCL bit could
      not be set for the page.

      PEI Code (66) Page UnPin Failure 3              (QSBUP66)
      The number of times CP Millicode could not unpin a page
      because an underflow of the PGSTE pin count would occur.

      PEI Code (67) Page UnPin Failure 4              (QSBUP67)
      The number of times CP Millicode could not unpin a page
      because the page-invalid (I) bit in the PTE is one for the
      page.

      PEI Code (68) Page UnPin Failure 5              (QSBUP68)
      The number of times CP Millicode could not unpin a page
      because the contents of the PTE page-frame-real-address
      (PFRA) indicate a page that is different from the frame
      specified for the page by the host SBALE for the page.
