Changes since v1:
- Use error_abort for getters (Igor)
- Free the device list (Igor)
- Refactor the NVDIMM related portion into hw/acpi/nvdimm.c (Igor)
- Rebase onto latest master
- Add Jingqi's Reviewed-by

On the command line, one can specify a NUMA node for NVDIMM devices. If
we set up the topology to give NVDIMMs their own nodes, i.e. not
containing any CPUs or regular memory, qemu doesn't populate SRAT memory
affinity structures for these nodes. However the NFIT does reference
those proximity domains.

As a result, Linux, while parsing the SRAT, fails to initialize node
related structures for these nodes, and they never end up in the
nodes_possible map. When these are onlined at a later point (via
hotplug), this causes problems.

I've followed the instructions in bios-tables-test.c to update the
expected SRAT binary, and the tests (make check) pass. Patches 1 and 3
are the relevant ones for the binary update.

Patch 2 is the main patch which changes SRAT generation.

Vishal Verma (3):
  diffs-allowed: add the SRAT AML to diffs-allowed
  hw/acpi-build: account for NVDIMM numa nodes in SRAT
  tests/acpi: update expected SRAT files
