"WARNING: workqueue cpumask: online intersect > possible intersect". This is because per node workqueue possible mask is set very early in the boot process even before the system was querying the home node associativity. However per node workqueue online cpumask gets updated dynamically. Hence there is a chance when per node workqueue online cpumask is a superset of per node workqueue possible mask.
