Subject: [PATCH 0/3 V8] workqueue: Introduce low-level unbound wq sysfs cpumask

The patchset is based on 4.1-rc1. And only the [PATCH 3/3]
is changed:

 1) Rename again. wq_unbound_global_cpumask -> wq_unbound_cpumask
    workqueue_set_unbound_global_cpumask() -> workqueue_set_unbound_cpumask()

 2) the code sets the wq_unbound_cpumask at first before applying it to
    all the wqs. It simplifies the code where it is applied to the wqs.

 3) When the user configured cpumask doesn't overlap with the low
    level cpumask, the V7 patchset forced the per-node pwqs use
    the default pwq and caused some complications. This patch
    just uses the default pwq's attrs to calculate the per-nodes' attrs
    and avoid introducing any branch or special handling.

Frederic Weisbecker (1):
  workqueue: Create low-level unbound workqueues cpumask

Lai Jiangshan (2):
  workqueue: split apply_workqueue_attrs() into 3 stages
  workqueue: Allow modifying low level unbound workqueue cpumask
