This is to create sysfs file for new node. It adds arch specific functions 'arch_register_node()' and 'arch_unregister_node()' to IA64 to call the generic function 'register_node()' and 'unregister_node()' respectively. (Each arch defines like sysfs_nodes[] to describe its nodes topology. I'm not sure they can be merged as generic code.)
