MCKBK Prolog

 NAME       : HCPMCKBK
 DESCRIPTION: MACHINE CHECK DESCRIPTOR BLOCK
 DSECT      : MCKBK
 FUNCTION   : THE MCKBK IS THE MAIN WORK AREA OF THE MACHINE-CHECK AND
              CHECK-STOP HANDLERS.  THE FIRST PART CONTAINS 'FOOTPRINT'
              FLAGS, AND A LOCAL TRACE TABLE FOR MACHINE CHECKS, AND
              OTHER STATUS FIELDS THAT MIGHT BE USEFUL IN DEBUGGING.
              THIS FIRST PART OF THE MCKBK IS APPENDED TO (AND RECORDED
              WITH) THE ERROR RECORD AND IS OCCASIONALLY REFERRED TO AS
              THE 'DAMAGE ASSESSMENT AREA'.  THE SECOND PART OF THE MCKBK
              IS NOT REGARDED AS VALUABLE FOR DEBUGGING AND CONSEQUENTLY
              IS NOT INCLUDED IN THE RECORDED ERROR RECORD.  THIS PART
              OF THE MCKBK IS SOMETIMES REFERRED TO AS THE 'MACHINE-CHECK
              WORK AREA'.
              DATA IS PLACED IN THE MCKBK AT THE START OF AN ERROR
              INCIDENT (MACHINE CHECK OR CHECK-STOP) AND, FOR THE MOST
              PART, IS NOT CLEARED UNTIL THE START OF THE NEXT INCIDENT.
 LOCATED BY : A CPU'S MCKBK IS ANCHORED IN THE CPU'S PREFIX PAGE,
              POINTED TO BY PFXMCHA.
 CREATED BY : HCPMPS    WHEN A PROCESSOR IS INITIALIZED.  EACH CPU HAS
              ONE OF THESE BLOCKS, ALLOCATED AT SYSTEM
              INITIALIZATION TIME OR WHEN THE CPU IS VARIED
              ONLINE.
              NOTES      : TO ACCOMODATE APPENDING THE MCKBK TO THE
              ERROR RECORD (MCHREC), THE MCHREC AND THE MCKBK
              ARE ALLOCATED FROM A SINGLE BLOCK OF STORAGE.
 DELETED BY : HCPMPS    TWO MINUTES AFTER A PROCESSOR IS VARIED OFFLINE.
 RELOCATION CONSIDERATIONS : None
