 NAME       : HCPSI2GB
 DESCRIPTION: SIE STATE DESCRIPTION (Format 2)
 DSECT      : SI2BK
 Function   :
              This control block describes a guest (virtual
              machine) to the interpretive-execution facility
              of the machine (embodied in the SIE instruction).
              It defines a SIE format-2 state description, which
              is the operand of a host SIE instruction when CP is
              running as an ESAME mode host. The SIE state
              description used by the host control program to run
              a guest is imbedded in the VMDBK, which is
              described by HCPVMDBK COPY.
              The SIE state description is also used by a guest
              control program operating in ESAME mode to run a
              virtual guest. In that context, it is the operand
              of a guest SIE instruction.
              This control block is defined by processor
              architecture.

 Comments   :
 As noted abo e, VM uses the state description in two
 contexts:
 1) It is imb dded within the VMDBK which we use to
              represent first-level guests (RGuests) when we issue
              the SIE instruction to run those guests.  In this
              case, we refer to it as a SIEBK.
              Some of the comments on fields below apply only to the
              SIEBKs which are imbedded in RGuest VMDBKs.  Those
              comments are surrounded by the annotation:
              [VMDBK only: . ].
 2) It is an  rgument of an RGuest's SIE instruction.
              In this context, it is not associated with a VMDBK --
              at least, our usage can not depend on such an
              association, as we are limited to the interface
              specified by the interpretive-execution architecture.
              When referring to such a state description, we call it
              an SI1BK (if the RGuest is in ESA/370 or ESA/390 mode)
              or an SI2BK (if the RGuest is in ESAME mode).
              Note that in processing such a state description, we
              will translate it into a "shadow" state description
              imbedded in a vSIE VMDBK; we may thereafter refer to
              it as a SIEBK.  In general, "[VMDBK only:]" comments
              do not apply to the SIEBKs in vSIE VMDBKs.
