mm, sparse: pass nid instead of pgdat to sparse_add_one_section()
Since the information needed in sparse_add_one_section() is node id to allocate proper memory, it is not necessary to pass its pgdat. This patch changes the prototype of sparse_add_one_section() to pass node id directly. This is intended to reduce misleading that sparse_add_one_section() would touch pgdat.
