When POWER10 CPU was made as default, we missed keeping POWER9 as
default for older pseries releases (pre-10.0) at that time.
This caused breakge in default cpu evaluation for older pseries
machines and hence this fix.
Should we also include:

?
I guess so. Not sure if we need a patch v2 for just that.

This is confusing because v9.2 has already been released with that...
I think it still needs to be fixed for v9.2 (and older) if someone wants
to use pseries-9.2 (and older) with future releases.
Gave it another thought. May be moving the default to v9.1 could be
relatively better. 9.2 stable shall get the fix for pre-9.2 but 9.2
default need not change.
Nick, Daniel, comments?
