Subject: [PATCH] rules: online CPU automatically on IBM s390x platforms when
configured
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
RHEL-only
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
