Subject: Revert "workqueue: Don't call cpumask_test_cpu() with -1 CPU in wq_update_node_max_active()"
From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
This reverts commit 7df62b8cca38aa452b508b477b16544cba615084 which is
commit 15930da42f8981dc42c19038042947b475b19f47 upstream.
The workqueue patches backported to 6.6.y caused some reported
regressions, so revert them for now.
