 NAME       : HCPQCIBK
 DESCRIPTION: Query Counter Information Block
 DSECT      : QCIBK
 FUNCTION   : Mapping of the Query Counter Information Block which is
              used to obtain CPU-Measurement Counter Facility
              information for this system.
 LOCATED BY : RCCQCTRI, a table of 4-byte addresses indexed by
              CPU address.
 CREATED BY : Subroutine GetQCIBK in HCPCCF ASSEMBLE the first time
              a CPU is going to issue a QCTRI instruction.
 DELETED BY : This control block is not deleted.  It persists for
              the life of the system for RAS purposes.  However,
              it is reused when a CPU issues a subsequent QCTRI.
 REFERENCES : none
 SERIALIZED : Processor local serialization with no loss of control
              serializes access to the data in this control block.
              Once allocated, this control block is only used
              by the CPU on which it was allocated.
 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.
