Subject: ppc/spapr: fix default cpu for pre-9.0 machines.
X-Git-Tag: v10.0.0-rc1~6^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1490d0bcdfcb78b4503cae42353d3dd50f4e9d96;p=thirdparty%2Fqemu.git

ppc/spapr: fix default cpu for pre-9.0 machines.

When POWER10 CPU was made as default, we missed keeping POWER9 as
default for older pseries releases (pre-9.0) at that time.
This caused breakge in default cpu evaluation for older pseries
machines and hence this fix.
