Subject: acpi: map pxms to low node ids
From: David Rientjes <rientjes@xxxxxxxxxx>
pxms are mapped to low node ids to maintain generic kernel use of
functions such as pxm_to_node() that are used to determine device
affinity. Otherwise, there is no pxm-to-node and node-to-pxm matching
rule for x86_64 users of NUMA emulation where a single pxm may be bound to
multiple NUMA nodes.
