Hello,

Make wq_online_cpumask more consistently which also simplifies the code, and
make unbound pwq updates from CPU hotplug path asynchronous so that we don't
add additional dependency on fork from CPU hotplug.

0001-workqueue-Make-wq_affn_dfl_set-use-wq_online_cpumask.patch
0002-workqueue-Make-wq_update_node_max_active-use-wq_onli.patch
0003-workqueue-s-unbound_wq_update_pwq-update_unbound_pwq.patch
0004-workqueue-Make-unbound-pwq-updates-from-CPU-hotplug-.patch

The patches are also available in

git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git use-wq_online_cpumask

diffstat follows. Thanks.
