So we will go with the following.
/*
 * We do not want to confuse userspace by sysfs files/directories for node
 * without any memory attached to it, so this node is not marked as
 * N_MEMORY and not marked online so that no sysfs hierarchy will be
 * created via register_one_node for this node. The pgdat will get fully
 * initialized by hotadd_init_pgdat() when memory is hotpluged into this
 * node
 */

OK?
