Vitaly Kuznetsov requested to merge vkuznets/centos-stream-9:RHEL-34602 into main Jun 06, 2024

JIRA: https://issues.redhat.com/browse/RHEL-34602
Upstream Status: RHEL-only

Switching Xen HVM guests to x2apic mode led to CPU onlining problems on AWS instance types. The issue is also reproducible with upstream kernel. For the time being, revert RHEL9 change to avoid the regression.
