Fix CPU hotplug regression on s390x introduced by commit 94c7e260b499 ("rules:
|
||
|
|
do not online CPU automatically on IBM platforms"). After discussion with IBM,
|
||
|
|
CPUs should be auto-enabled when in the configured state after a hotplug.
|
||
|
|
However, if the CPU is deconfigured, it should not.
|
||
|
|
|
||
|
|
This is because on zVM and KVM hotplugged CPUs are configured and on LPAR/DPM
|
||
|
|
they are deconfigured.
|
||
|
|
|
||
|
|
Resolves: #2212612
