Subject: hot-add-mem x86_64: use CONFIG_MEMORY_HOTPLUG_RESERVE
From: Keith Mannthey <kmannth@xxxxxxxxxx>
The api for hot-add memory already has a construct for finding nodes based on
an address, memory_add_physaddr_to_nid. This patch allows the fucntion to do
something besides return 0. It uses the nodes_add infomation to lookup to
node info for a hot add event.
