Subject: [RFC PATCH 0/5] workqueue: Introduce low-level unbound wq sysfs cpumask v3

So in this version I actually save the cpumask belonging to wq (before
it's intersected against the low level cpumask) in its unbounds attrs.

But the attrs passed to pwq and worker pools have the low level cpumask
computed against the wq cpumask.

It makes it easier that way as the wq cpumask itself remains untouched.
It's a user setting so it must stay intact. OTOH the cpumask of pwqs and
worker pools only belong to the implementation so it's the right
place to store the effective cpumask.

Also wq_update_unbound_numa() is fixed, and cpu_possible_mask() 
is restored as a base. Thanks to Lai!

Thanks,
	Frederic
