[GIT PULL] workqueue fixes for v4.5-rc3

[Tejun Heo]

Hello, Linus.

Workqueue fixes for v4.5-rc3.

* Remove a spurious triggering of flush dependency warning.

* Officially break local execution guarantee of unbound work items and
  add a debug feature to flush out usages which depend on it.

* Work around CPU -> NODE mapping becoming invalid on CPU offline.

The branch is young but pushing out early as stable kernels are being
affected.

Thanks.
