     NAME       : HCPSVGBK
     DESCRIPTION: Linkage savearea, longreg format
     DSECT      : SVGBK
     FUNCTION   : The SVGBK is used in the call-with-dynamic-savearea
                  calling linkage to a "long-register", or "longreg",
                  routine (one which uses 64-bit registers when the
                  machine provides them).  The
                  caller does not supply the savearea.  Instead, the
                  linkage assistance routines (HCPSVC/SVD) allocate
                  the SVGBK and the called routine then saves the
                  caller's registers in the SVGBK.
                  Shortreg routines (those which always treat
                  registers as 32 bits) use an SAVBK instead of an
                  SVGBK.
                  The SVGBK dsect is also used as a map of the
                  several fixed saveareas such as PFXBALSV and
                  PFXTMPSV, when they are used by longreg and routines.
                  Finally, the SVGBK can be used as a longreg
                  alternative to a CPEBK.  (There is no "CPGBK".)
                  HCPSTK will accept an SVGBK to be stacked for later
                  dispatching by HCPDSB.
     LOCATED BY : R13       when running in any "long-register"
                  routine which is called using a
                  call-with-dynamic-savearea linkage.
                  Points to current (already filled up)
                  savearea.
                  SVGR13    This field in callee's savearea points
                  back to the callers savearea.  (This
                  assumes that the caller is a longreg
                  routine and has a savearea of its own,
                  and that he had its address in
                  R13 at the time of the call.  See also
                  SVGCSAV for another backward pointer.)
                  SAVEFPNT  forward chaining pointer.  The chain of
                  /SVGFPNT  available SVGBK's uses this pointer.
                  When the SVGBK is in use as a savearea,
                  SAVEFPNT is normally not used for
                  anything.  (SAVER13 points back to the
                  preceding SVGBK/SAVBK if the caller
                  had one.)
                  SAVEBPNT  This pointer is available for backward
                  /SVGBPNT  chaining, but is not normally used.
                  VMDQURCP  Urgent CPEBK/SVGBK stack
                  VMDQCPEF  Normal CPEBK/SVGBK stack
     CREATED BY : HCPSVC    when no free SVGBKs are available
                  HCPSAM    during processor online storage
                  allocation
     DELETED BY : HCPSVC    during SVGBK reclaim processing
                  HCPSAM    during processor offline storage
                  deallocation
     REFERENCES : The front of the SVGBK is a header, the SVHBK,
                  which is common among the CPEBK, SAVBK, and SVGBK.
                  Chains threaded through SVGFPNT/-BPNT may contain
                  a mix of SVGBKs and CPEBKs or SAVBKs.
     SERIALIZED : Dispatch lock for all fields except SVGCPRQ,
                  except for SVGCPRQ, which is serialized by TRQBK
                  and by the MP-defer function.
     COMPATIBILITY AND MIGRATION CONCERNS :
     RELOCATION CONSIDERATIONS : None
     COMMENTS   : SVGFPNT and SVGBPNT are used to maintain various
                  SAVBK/CPEBK/SVGBK queues and stacks.  Routines may
                  use these fields if the SVGBK is not currently on a
                  queue or stack.  An example is the SVGBK used on a
                  dynamic call.
                  If a routine calls another routine to stack an
                  SVGBK onto a queue, the calling routine should be
                  aware that the SVGFPNT and SVGBPNT fields may have
                  been changed as a result of the call.  The calling
                  routines should refrain from using these fields.
