RH-Commit: [5/5] da022e5acaeb1c86fba6245aa2c20491ac83046f (thuth/qemu-kvm-cs9)
|
|
|
|
Upstream-Status: N/A
|
|
|
|
We now completely disable the old CPU models up to the z12 in
|
|
target/s390x/cpu_models.c, so we don't need these old checks
|
|
anymore.
|
|
|
|
This patch should get squashed into the downstream patch
|
|
"Enable/disable devices for RHEL" during the next rebase.
