 NAME       : HCPSTFLE
 DESCRIPTION: STFLE response mapping
 DSECT      : STFLE
 FUNCTION   : Map STFLE response in HCPRCCFL
 LOCATED BY : HCPRCCFL
 CREATED BY : not a control block, just a DSECT, so not created
 DELETED BY : see above
 REFERENCES : none
 SERIALIZED : N/A
 COMPATIBILITY AND MIGRATION CONCERNS : N/A
 NOTES      : This DSECT is used to map the data from the
              STFLE instruction that is issued during system
              initialization.
              Note that the first four bytes of output from
              both the STFL and STFLE instructions are the
              same and are stored at location PFXSTFL.  The
              bytes defined at PFXSTFL are used to address
              these four bytes from both instructions.
              This DSECT is the method to address STFLE
              bytes 4 and up, and may also be used to address
              STFLE bytes 0 through 3.  The bit definitions
              in HCPEQUAT are used with both this DSECT and
              PFXSTFL to address individual bits.

                                        function selectively. In both

                                        means the TLB purging is limited
