SCLP Info Area Lock:
This lock must be held shared if SYSSCPBK, the pointer to
the SCP Info Area is used to access the SCP Info across a
loss of control. If a 'snapshot' access is done using
SCPSCPBK, without loss of control, the lock is unnecessary
since the release of the SCP Info area is done via an
MPDFR call to HCPSASRL. This lock is meant to prevent
the SCP Area being release because of an SCLP Configuration
Management Data event, event qualifier 4, which may change
the installed CPU facilities.

value is contained in SYSNGMAX.
This value is initialized to CP's
native value, but an ESM can
provide a larger number. A
POSIX-capable ESM is required to
notify CP of its presence and its
{NGROUPS_MAX} value. The SYSPXESM
byte is manipulated with TEST AND

sets it to X'FF' will modify
SYSNGMAX. Thus the ESM may supply
its {NGROUPS_MAX} value only
once.
