 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.
