commit c7b14d3af7 ("s390x/s390-virtio-ccw: Switch off zPCI enhancements
7f1c5b
on older machines") activated zPCI enhancement features (interpretation
7f1c5b
and forward assist) silently on the s390-ccw-virtio-rhel8.6.0 machine
7f1c5b
for RHEL8.8. It didn't seem to be a problem since migration is not
7f1c5b
possible but it broke LEAPP upgrade to RHEL9 when the machine is
7f1c5b
defined with a passthrough device. Activate the zPCI features also on
7f1c5b
RHEL9.2 for the machines to be alike in both latest RHEL distros.
