Based on physical memory hot-remove functionality, we can implement
node hot-remove. But there are some problems in cpu driver when offlining
a node. This patch-set will fix them.
All these patches are based on the latest -mm tree.

Tang Chen (1):
Do not use cpu_to_node() to find an offlined cpu's node.
Wen Congyang (4):
cpu_hotplug: clear apicid to node when the cpu is hotremoved
memory-hotplug: export the function try_offline_node()
cpu-hotplug, memory-hotplug: try offline the node when hotremoving a
cpu
cpu-hotplug,memory-hotplug: clear cpu_to_node() when offlining the
node
