But in case of CONFIG_USER_ONLY, we return the flags returned by
s390_probe_access(), not a PGM__* value. Maybe it doesn't matter,
because we'll simply inject a SIGSEGV in any case ...
I would have said it would matter for MVPG, except that is incorrectly *not* marked as a
privileged instruction. There should be no CONFIG_USER_ONLY case to answer there.
Ho hum, misread that -- only privileged if access key specified (and we do not check or
support those).
