Subject: [PATCH v2 0/2] Specify empty NUMA node

There are multiple empty nodes, where no memory resides in, are allowed
in virtual machine (VM) backed by QEMU. I don't find anywhere to document
how the corresponding device nodes are populated. This series adds one
section in Documentation/devicetree/bindings/numa.txt to document how
the empty NUMA nodes are handled: no device nodes are existing for these
empty NUMA nodes, but the NUMA IDs and distance map are still valid in
"numa-distance-map-v1" compatible device node.

PATCH[1] adds one section in Documentation/devicetree/bindings/numa.txt
         to specify how device nodes are populated for these empty NUMA
         nodes.
PATCH[2] fetches NUMA IDs and distance maps from "numa-distance-map-v1"
         compatible device node.

Changelog
=========
   * No device nodes for empty NUMA nodes                     (Rob)
   * Add patch to fetch NUMA IDs and distance map from the
     "numa-distance-map-v1" compatible device node            (Rob)
