Subject: hotplug cpu move tasks in empty cpusets to parent node_online_map fix
From: Cliff Wickman <cpw@xxxxxxx>
As of the October 2007 kernel/cpuset.c patch "Memoryless nodes:
Use N_HIGH_MEMORY for cpusets", cpuset nodes are relative to
the nodes with (HIGH) memory, not relative to all nodes in
node_online_map.
