And in x86, the definitions are protected by CONFIG_MEMORY_HOTPLUG. memory_add_physaddr_to_nid() uses numa_meminfo to find the physical address's nid. It has nothing to do with memory hotplug. And also, it can be used by alloc_low_pages() to obtain nid of the allocated memory. So in x86, also use CONFIG_NUMA to protect it.
