      The number of guest QDIO-asynchronous operation blocks
      (QAOBs) that firmware couldn't handle for a guest-issued

      Long Term Pin Notification UnPinning a Page     (QSBLTUPN)
      The page designated by the storage-block-index (SBIX)
      field could not be UNPINNED because pin-notification field
      (PGSTE.PN) specifies a code of 2 or 3 and it is a final
      unpin.  This PEI will only occur when requested by z/VM
      when the "(4) Long Term" bit is turned on in QFLAGS field
      of the QBICB (QIOBK).

      Long Term Pin Notification Pinning a Page       (QSBLTPIN)
      The page designated by the storage-block-index (SBIX)
      field could not be PINNED because pin-notification field
      (PGSTE.PN) specifies a code of 2 or 1 and a long-term pin
      was requested.  This PEI will only occur when requested by
      z/VM when the "(4) Long Term" bit is turned on in QFLAGS
