Something happened in the 4.13.2 release which broke the nvidia driver.

A few symbols changed and there was something that flipped to a GPL
labelled symbol.

I know we don't directly provide that for various reasons, but there is the
initiative with Negativo etc that the Workstation Working Group has
highlighted several times.

See these posts:

https://devtalk.nvidia.com/default/topic/1023822/linux/-p...

It refers to 4.14-rc1 but I saw the identical issues on 4.13.2-200 with
this.

Is this something worth holding back on the kernel release on F26 for the
time being?
