I verified that the performance is the equivalent of upstream with
3.13.0-32-generic. There is still work to be done upstream but this gets
us quite a bit further.

Title:
  Support memoryless nodes in Ubuntu kernel

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Trusty:
  Fix Committed
Status in “linux” source package in Utopic:
  Fix Released

Bug description:
  Several patches have gone upstream recently that improve powerpc's
  handling of memoryless nodes. These can be present in guests, but more
  importantly can be seen in Power8 host/PowerNV systems due to the
  manufacturing population of DIMMs.

  Upstream commits:

  81c98869faa5f3a9457c93efef908ef476326b31 (kthread: ensure locality of
  task_struct allocations)

  844e4d66f4ec3b6b6d3bcfcfba3ade2b962771e2 (slub: search partial list on
  numa_mem_id(), instead of numa_node_id())

  8c272261194dfda11cc046fbe808e052f6f284eb (powerpc/numa: Enable
  USE_PERCPU_NUMA_NODE_ID)

  64bb80d87f01ec01c76863b61b457e0904387f2f (powerpc/numa: Enable
  CONFIG_HAVE_MEMORYLESS_NODES)
