Bugzilla: 1693772
|
|
Upstream: n/a (downstream only)
|
|
|
|
Since we skipped the -rhel8.0.0 machine on s390x, we have to add the
|
|
related compatibility properties now to the -rhel7.6.0 machine type
|
|
instead.
|
|
|
|
Also the "multiple epoch" facility was disabled on the z14GA1 CPU
|
|
in 7.6, so we also have to adjust our machine type here accordingly.
