Title:
  SRU request: dkms build fails with zesty hwe kernel [error: too few
  arguments to function ‘NV_GET_USER_PAGES’]

Status in nvidia-graphics-drivers-340 package in Ubuntu:
  Fix Released
Status in nvidia-graphics-drivers-340 source package in Xenial:
  Fix Released

Bug description:
  SRU Request:

  [Impact]
  The patch for Linux 4.9 in nvidia-340 in Ubuntu 16.04 does not match the one in 17.04. As a result, the module fails to build against the hwe 4.10 kernel.

  [Test Case]
  1) Enable the xenial-proposed repository, and install linux-headers-generic-hwe-16.04-edge, linux-image-generic-hwe-16.04-edge, and nvidia-340.

  2) Check that DKMS builds the module, then restart the system, and see
  if it boots correctly. If unsure, please attach your /var/log/gpu-
  manager.log and /var/log/Xorg.0.log

  [Regression Potential]
  Low, the exact same patch is already available in the package in 17.04.

  We need to backport build fixes for 4.9/4.10 kernels.
