[PATCH] Register sysfs file for hotplugged new node
When new node becomes enable by hot-add, new sysfs file must be created for new node. So, if new node is enabled by add_memory(), register_one_node() is called to create it. In addition, I386's arch_register_node() and a part of register_nodes() of powerpc are consolidated to register_one_node() as a generic_code(). This is tested by Tiger4(IPF) with node hot-plug emulation.
