        STSI response data areas.
        Function   :  A managed, in memory copy of STSI output.
                   The following STSI responses are maintained:
                   1.1.1 and 1.2.2.
                   For STSI 1.1.1 and 1.2.2, an additional pair
                   of data areas is maintained that contains
                   the most recent responses with non-transient
                   states indicated. See SSI1TRNS and HCPSSICC.
                   These are needed for Diagnose x'2E0'.
                   References to these data areas during CP
                   initialization must test the pointers to
                   ensure they are initialized (nonzero pointer)
                   before using the response areas.
                   HCPSSIBK maps the STSI responses.
        Serialized :
                   These data areas are updated only during
                   system initialization while running on a
                   single processor, or later while running on
                   the SYSTEM VMDBK.
                   Each time the STSI responses are updated, a
                   new data area is allocated and the pointers
                   below are updated. The prior response area
                   is released by an MPDFR call to HCPSSIRL to
                   allow existing references to continue to use
                   the old response areas until their next loss
                   of control.
                   No serialization is provided to consumers of
                   these data areas that allows access over a
                   loss of control. The STSI response area may
                   have been released during the loss of control.
                   No form of serialization can provide a
                   self-consistency guarantee for the pair of
                   responses for STSI 1.1.1 and 1.2.2 since
                   changes may occur between the STSI instruction
                   invocations that affect values reported in
                   both STSI responses. For example, changes to
                   capability values reported by STSI 1.2.2 may
                   be explained by corresponding changes to CCR
                   and CAI values reported by STSI 1.1.1.

        RCCEMSxx:  EMSBK Cleanup Counts and Type flags
        Function   :  Track statistics for cleanup of EMSBKs found
                   on the PFXPG of a processor during VARY
                   processing. The individual counts are for
                   different points in the processing of
                   VARY OFF PROC/CORE and VARY ON PROC/CORE.
                   If the EMSBKs are cleaned up after
                   the HCPMPCLF processing,
                   then the EMSBKs may have been waiting to be
                   processed for 2 minutes or more. This should
                   be avoided because the result will be that
                   the tasks waiting for completion of HCPSGP's
                   processing will appear to hang while the
                   EMSBK is on the PFXEMSAN queue. Currently,
                   this is only the case for HCPSGPNC's callers
                   indicated by RCCEMSNF.RCCEMSNC being on.
                   There should be a count field and flag byte
                   for each caller of HCPSGPDR.

        STSI 15.1.x response data area & system topology fields
        Function   :  To save System Topology (STSI 15.1.x) data
                   and counters related to how often the data
                   has been updated.  A lock is defined as these
                   fields can only be updated when the lock is
                   held exclusive and can only be read/copied
                   when the lock is held shared.
                   System Topology data is saved in storage for
                   1st level CP systems.  Periodically, CP polls
                   (via PTF FC 2) to determine if the system
                   topology has changed. If it has, STSI 15.1.x
                   is issued to update the System Topology data
                   in storage.
                   When monitor needs to cut a system topology
                   configuration record (D1R26) or an event
                   record (D5R14), the fields are copied while
                   the lock is held shared to ensure the values
                   are not being updated at the time.  The lock
                   is released before the copied data is passed
                   to the monitor routine because monitor might
                   lose control while processing the data.
                   HCPSSIBK maps the STSI responses including
                   the first part of the STSI 15.1.x response.
        Serialized :
                   The following data areas are serialized by
                   the Topology lock (HCPDSVTL).  This lock must
                   be held as follows to ensure these fields are
                   kept in sync and apply to the same instance
                   of system topology (STSI 15.1.x) response:
                   EXCLUSIVE:
                    * Whenever any of the fields are changed.
                    * For STSI data updates, the lock must be
                      held from BEFORE the PTF FC 2 until after
                      the STSI 15.1.x is issued to ensure the
                      saved STSI data is the most current.
                   SHARED:
                    * Whenever 2 or more fields are read/copied
                      and need to be in sync with each other.
                   This lock is *NOT* to be held over a loss of
                   control.

014C  332 Signed       4 RCCREBAL       Count of the number of times a
                                        rebalance was done on this
                                        system.
        The following fields are used to build two arrays of
        origin VMUBKs for use by the DSVBK rebalance routine.
        Storage for the array is obtained at system IPL time.
        The arrays are rebuilt each time the guest CPU usage
        prediction routine is called.  The prediction routine
        is called by the Periodic HiperDispatch routine before
        it calls the rebalance routine.
        There are two arrays built because rebalance wants to
        assign new home DSVBKs first to the guests with the
        largest predicted future CPU usage.  So the first array
        is built unordered at the beginning of this buffer and
        then a quick sort is done to order them by predicted
        usage.  The second array is maintained at the end of
        the buffer working backward through the buffer.  This
        This array contains all origin VMUBKs whose predicted
        CPU usage is below a certain threshold as defined in
        HCPVMU.  This second array is built to make the quick
        sort as efficient as possible by keeping the potentially
        large number of inactive guests out of the array that
        needs to be sorted.  There is very little difference in
        the predicted CPU usage of all of these guests and so
        no real need to sort them.
        Serialization of these arrays is accomplished with the
        RCCVMULK defer lock.  This lock is obtained at the
        time the arrays are populated with VMUBK addresses.
        This is done early in the Periodic HiperDispatch routine
        which is driven once every two seconds.  The lock is
        held from the time population of the arrays begins
        until near the end of the Periodic HiperDispatch routine
        processing when the rebalance function completes.
        This lock is held to ensure no VMUBKs in either array
        can be released by logoff before all of the rebalance
        function completes.  Note that because this lock is
        obtained early and held continuously across most of the
        Periodic HiperDispatch routine, other locks are obtained
        after RCCVMULK was obtained.  Therefore RCCVMULK must
        always be obtained prior to obtaining any of the
        following:  vary lock, scheduler lock, topology lock.
        An entry (element) in the arrays consists of two fields
        which are mapped by the VMUARYEN DSECT in HCPVMUBK:
        1) a fullword pointer to an origin VMUBK
        2) a fullword CPU usage value which is a scaled
           percentage of the guest's total predicted CPU usage
           for the next interval.

      These routines cannot be re-entered until the next timer

      Similar to RCCWHIBK above, RCCNUPK is serialized by being
      set and used in sequential routines executed after a timer
      pop.  RCCNUPK is set in HCPHIC when the decision about
      which CPUs should be in the unparked state is made.
      RCCNUPK is later used when creating the park/unpark
      decision monitor event record.  The timer is not restacked
      until after the monitor record has been generated, thus
      preventing HCPHIC from running again and modifying this
      field until it has been consumed.

      Similar to RCCWHIBK and RCCNUPK, RCCOSCCT is serialized by
      being set and used in sequential routines executed after a
      timer pop. RCCOSCCT is used in HCPHICCC to decide whether
      to leave one extra CPU unparked to avoid park/unpark
      oscillation.
01C4  452 Signed       2 RCCOSCCT (6)   Array of times in a row that
                                        HCPHICCC has predicted it will
                                        need exactly one less CPU than it
                                        currently has unparked. Indexed
                                        by CPU type.
      These arrays are allocated for two purposes:
        1. When CP is running in a dedicated partition, they
           (RCCTUTIL and RCCTTIME) are used in calculating
           utilization which must be done differently when the
           logical processors are dedicated to physical
           processors.
        2. Calculating a (per-CPU-type-pool) T/V ratio.  That
           is, within a given CPU type, a ratio of non-wait
           execution time to guest emulation (run under SIE)
           time.  This is used when making park/unpark decisions
           to gauge the potential MP overhead savings by parking
           a CPU.
      The arrays have MAXRPROC doubleword entries and are
      indexed by cpu address.  At each interval the value of
      non-wait execution time in microseconds since the CPU was
      brought online is calculated using PFXTMSYS and PFXUTIME.
      HCPWHI calculates utilization for the interval as the
      difference from the non-wait execution time of the prior
      interval.  The same calculation is performed for guest
      emulation time.

        RCCxCAPy:  CPU Capability formats from STSI 1.2.2
                   in integer and binary floating point formats.
                   - If the secondary value (integer or BFP) is
                     zero, then all processors have the same
                     capability, reflected in the primary value.
                   - If the nominal value (integer or BFP)
                     is zero, then processors are currently
                     operating at their nominal capability,
                     reflected in the primary or secondary value.
                   - Integer values are rounded from BFP values,
                     except that a near-zero BFP value is
                     rounded up to integer 1.
        Function   :  In zEC12 and earlier machines, STSI 1.2.2
                   reports only integer values for CPU
                   capability fields.  In z13 and later
                   machines, the CPU capability is given as
                   an integer or as a binary floating point
                   number.  We want to store both values for
                   all architectures for monitor and accounting
                   records' backward compatibility.
