          NOTE : This field VMDMMODE was used to consolidate the
                 SIE descriptor representation for a machine mode.
                 Now the machine mode type, which includes ESA/XC,
                 may change dynamically,
                 it is NOT practical to expand this field to include
                 the new machine modes.
                 The function of this field to test the machine mode
                 is replaced by the HCPVMODE macro.

          VMDMESA  = SIEXA=1  and SIEMCDS=0 and SET MACHINE XA or ESA
          VMDMRG32 = SIEESAME=0  initial value at logon or reset
          VMDMRG64 = SIEESAME=1  and set if machine issues SIGP Set

           NOTES      : The SET MACHINE XA is remembered in VMDMFEAT for the
                 following commands: Q SET and INDICATE.(VMDSETXA bit)
                 The reason there isn't a separate VMDMXA is that CP
                 will only run on ESA hardware therefore a XA mode
                 machine is the same as an ESA mode machine.
           NOTES      : Either VMDMRG32 or VMDMRG64 will always be on.  For
                 a machine in ESA mode, either one can be on.  For a
                 370 or XC mode machine, VMDMRG32 will be on.
                 SET MACHINE ESA, represented by the VMDMESA bit,
                 has two subsets represented by the VMDMRG32 and
                 VMDMRG64 bits.  VMDMRG32 indicates the subset of ESA
                 architecture without ESAME enabled by SIGP Set
                 Architecture.  VMDMRG64 indicates the subset of ESA
                 architecture with ESAME enabled by SIGP Set Arch.
                 Within an ESA virtual machine, individual virtual
                 CPUs must all be in the same subset.

          VMDVLTBL is a VDEV lookaside table used to eliminate the

          lookaside (across  virtual CPUs) requires console function

    0818 2072 Dbl-Word     8 VMDPTIL (3)    Page Table Invalidation Lock
                 This lock is used in the base VMDBK to serialize use
                 and invalidation of architecturally "attached" DAT
                 structures associated with the virtual configuration,
                 including the ASTE, STD or ASCE, and region, segment,
                 and page tables.  A share of VMDPTIL must be held
                 while any tasks are dispatched which may access the
                 guest DAT structures implicitly via DAT, whether
                 actually running the guest under SIE or accessing
                 guest storage directly from DAT on CP code.  When
                 held shared by other tasks, it indicates to the ALR
                 tasks that an IPTE instruction is necessary to
                 invalidate private page table entries; if an ALR task
                 obtains PTIL exclusive, it need not IPTE to
                 invalidate page table entries.  It must be held
                 exclusive by any task making destructive changes
                 (such as invalidating PTEs without IPTE, invalidating
                 STEs or RTEs, changing attached region, segment, or
                 page table origins or lengths, changing the ASTE
                 STD/ASCE or VMDPSTD / VMDPASCE).  The dispatcher and
                 HCPACCES obtain PTIL shared so that implicit accesses
                 to the guest DAT structures will not occur while
                 other tasks are making potentially destructive
                 changes to those structures.
                 VMDPTIL is much like any other HCPLCK managed lock,
                 but there are substantial extensions, see the macros
                 HCPLKPTL, HCPULPTL, and HCPSWPTL for details.
                 Additionally, the following fields, VMDPTILB and
                 VMDPTILX, are in essence part of VMDPTIL, though part
                 of the non-HCPLCK superset.

                                      Set by IUCV and VMCF when:
                                a) A VMDBK uses IUCV or VMCF to
                                   communicate with another VMDBK
                                b) The protocol indicates a
                                   response is expected.
                                     Turned off in normal case when
                                     final response is sent to
                                     originating VMDBK.
                                     Turned off in an error-correction
                                     case by the scheduler.  Whenever
                                     a VMDBK begins a new transaction
                                     (by scheduler standards), then if
                                     the VMDBK has not just been
                                     readied to talk to an SVM (see
                                     VMDRDYCM flag, below), the
                                     scheduler assumes some mistake has
                                     been made.  (If the VMDBK ever
                                     went idle because it was waiting
                                     on an SVM, it should only have
                                     been readied when that reply was
                                     received.  Receiving the reply
                                     would have turned on VMDRDYCM.
                                     No intervening work is expected.
                                     Therefore, if the VMDRDYCM flag
                                     is off, the VMDSVMWT flag should
                                     also be off.)  The scheduler will
                                     correct the assumed mistake by
                                     turning off VMDSVMWT.  This
                                     precaution is taken in case the
                                     IUCV/VMCF protocol is used in an
                                     unexpected way, causing the
                                     VMDSVMWT flag to not get turned
                                     off in the normal case, in turn
                                     causing Monitor to see many

                                      at drop.  The scheduler never
                                      tests VMDSVMWT directly; instead
                                      it always tests this backup

                                      potentially be turned off
                                      already.  If the VMDBK went idle
                                      waiting for an SVM, then the SVM
                                      could send a reply, turning off
                                      VMDSVMWT before readying the
                                      VMDBK to process the reply.)
