NAME       : HCPCCFBK
 DESCRIPTION: CPU-Measurement Counter Facility Counters
 DSECT      : CCFBK
 FUNCTION   : Mapping of the CPU-Measurement Facility Counters
              for all supported Counter First Version Number (CFVN)
              and Counter Second Version Number (CSVN) combinations.
 LOCATED BY : PLSCCFBK
 CREATED BY : HCPMPS (when a PLSBK is allocated)
 DELETED BY : HCPMPS (when a PLSBK is released)
 REFERENCES : none
 SERIALIZED : Processor Local - updates are only made on the CPU
              whose PLSBK points to this instance of the CCFBK.
              Monitor Command Lock (MND_CMD_LOCK) - the collection
              task is serialized by this lock to prevent a race
              between two tasks collecting counters in the CCFBK
              on each CPU.
 RELOCATION CONSIDERATIONS : None
 COMPATIBILITY AND MIGRATION CONCERNS : The format of this control block is defined in "The
              Set-Program-Parameter and CPU-Measurement Facilities"
              book and should not be modified.  If new CFVN/CSVN
              combinations are created, new mappings will need
              to be added to support them.
