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.
