[PATCH] hot-add-mem x86_64: memory_add_physaddr_to_nid node fixup
In cases where the acpi memory-add event does not containe the pxm (node) infomation allow the driver to look up node info based on the address. The acpi_get_node call returns -1 if it can't decode the pxm info, this causes add_memory to panic. acpi_get_node would have to decode the resource from the handle (a lenghty proposition). This seems to be the cleanist point to interject the hook.
