Subject: node hotplug: register_node() fix
From: KAMEZAWA Hiroyuki <kamezawa.hiroyu@xxxxxxxxxxxxxx>
Create symblic link from newly-added-node to its cpus.
Ideally, node should be onlined before cpu-hot-add. But it cannot be always
achieved (at node-hot-add.)
This patch registers cpus to its node when the node is registered.
