Merge branch 'for-4.5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue fixes from Tejun Heo: "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" * 'for-4.5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: handle NUMA_NO_NODE for unbound pool_workqueue lookup workqueue: implement "workqueue.debug_force_rr_cpu" debug feature workqueue: schedule WORK_CPU_UNBOUND work on wq_unbound_cpumask CPUs Revert "workqueue: make sure delayed work run in local cpu" workqueue: skip flush dependency checks for legacy workqueues
