[GIT PULL] workqueue fixes for v4.15-rc1

[Tejun Heo]

Hello,

* Lai's hotplug simplifications inadvertently fix a possible deadlock
  involving cpuset and workqueue.

* CPU isolation fix which was reverted due to the changes in the
  housekeeping code resurrected.

* A trivial unused include removal.

Thanks.
