Pull workqueue fixes from Tejun Heo:
 "Two doc update patches and the following three fixes:
   - On single node systems, the default pool is used but the
     node_nr_active for the default pool was set to min_active. This
     effectively limited the max concurrency of unbound pools on single
     node systems to 8 causing performance regressions on some
     workloads. Fixed by setting the default pool's node_nr_active to
     max_active.
   - wq_update_node_max_active() could trigger divide-by-zero if the
     intersection between the allowed CPUs for an unbound workqueue and
     online CPUs becomes empty.
   - When kick_pool() was trying to repatriate a worker to a CPU in its
     pod by setting task->wake_cpu, it didn't consider whether the CPU
     being selected is online or not which obviously can lead to
     subobtimal behaviors. On s390, this triggered a crash in arch code.
     The workqueue patch removes the gross misbehavior but doesn't fix
     the crash completely as there's a race window in which CPUs can go
     down after wake_cpu is set. Need to decide whether the fix should
     be on the core or arch side"
