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:
In Progress
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.
