Title:
  [Ubuntu 16.04] NVLINK support for Garrison

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Xenial:
  Fix Committed

Bug description:
  This is a feature request to support NVLink for POWER8 processor and
  NVIDIA.

  We're still in early hardware bring up at this stage, but thankfully
  the kernel patches are reasonably small. At this stage I'm hoping to
  get the first version of the patches posted to the mailing lists in
  the next couple of days meaning that they will hopefully get into 4.5.

  Bug mirrored for Canonical awareness. A backport from 4.5 will be
  required once the patch is accepted.
