Merge branch 'linux-4.18' of git://github.com/skeggsb/linux into drm-next

The main thing here is the addition of support for Volta GV100 GPUs,
everything else basically restructuring display / graphics init code
to make it possible to fit Volta support in more nicely.

There's a bunch of improvements/fixes scattered in there for earlier
GPUs too, particularly graphics engine init on all GPUs from Fermi
onwards.

drm/nouveau/kms/nv50-: simplify tracking of channel interlocks

Instead of windows returning their core channel interlock mask if they
know core has been modified, it's recorded unconditionally and used if
required when update methods are emitted.

This will be required to support Volta.
