Just updated to Kernel 4.14.9, and normally this should not be anything to cause concern, but this time there has been a significant code change made, that has broken NVIDIA (384.98):

This sort of thing is expected in ‘testing’ -rc kernel versions, but is not supposed to occur in ‘mainline/stable’ versions..

It had already been mentioned in the Kernel mailing list:  http://lkml.iu.edu/hypermail/linux/kernel/1712.3/00099.html

Fortunately, there is a fix, and it is – somewhat ironically – the patch intended for Kernel 4.15 (see http://rglinuxtech.com/?p=2141 ), and with this, the compile/load completes successfully:

It remains to be seen whether this significant change to the stable 4.14 kernel series will be reverted, but – IMHO – it should be!

FYI.. I had seen a report that VMware 14.1.0 was also broken with Kernel 4.14.9, but it seems OK on my system..
