Bug#917586: other kernel change affecting nvidia

[Jiri Palecek]

Hello,

commit 
https://github.com/torvalds/linux/commit/ae2b01f37044c10e975d22116755df56252b09d8 
also affects nvidia. vm_insert_pfn is used in 
nvidia-drm/nvidia-drm-gem-nvkms-memory.c. It can be easily converted to 
vmf_insert_pfn, by removing the following switch (which only converts 
the errno to a vm fault, which vmf_... returns directly).

With this and the ipmi_user_t fixed, nvidia module can be compiled again.

Regards
