Hi,
So this new version takes another direction suggested by Tejun. Now we have a cpumask at the root of the workqueue directory to bound the affinity of all unbound workqueues.
It's an early release as more plumbing is required. Most notably:
* Drop last patch and integrate Lai's instead to support apply_workqueue_attrs() on ordered workqueues: https://lkml.org/lkml/2014/4/15/181
* Handle cpumask value expansion (in fact the per wq cpumask must be stored seperately than the effective cpumask to handle that correctly). I should take care of that in the next version.
But I prefer to post the current state now in case I'm wandering off.

Thanks, Frederic ---
