Oleg Nesterov d2ba7e2ae2 simplify cpu_hotplug_begin()/put_online_cpus() 
cpu_hotplug_begin() must be always called under cpu_add_remove_lock, this
means that only one process can be cpu_hotplug.active_writer.  So we don't
need the cpu_hotplug.writer_queue, we can wake up the ->active_writer
directly.

Also, fix the comment.
