Boris Ostrovsky aec03f89e9 ACPI/NUMA: Do not map pxm to node when NUMA is turned off 
acpi_map_pxm_to_node() unconditially maps nodes even when NUMA is turned
off. So acpi_get_node() might return a node > 0, which is fatal when NUMA
is disabled as the rest of the kernel assumes that only node 0 exists.

Expose numa_off to the acpi code and return NUMA_NO_NODE when it's set.
