[Part2 PATCH v4 10/15] x86, numa: Move memory_add_physaddr_to_nid() to CONFIG_NUMA.

From: Tang Chen
Date: Thu Jun 13 2013 - 09:28:28 EST

memory_add_physaddr_to_nid() is declared in include/linux/memory_hotplug.h,
protected by CONFIG_NUMA. And in x86, the definitions are protected by

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.
