Merge branch 'linux-4.21' of git://github.com/skeggsb/linux into drm-next

Mostly just initial support for Turing TU104/TU106 chipsets.  Support
for TU102 is missing as I don't yet have HW, but it should be trivial
to add in later in the merge window (in theory).

It's a bit of a rough first pass that'll get improved in future
releases as a finish figuring out some of the other HW changes, but
it's good enough as it stands for modesetting and suspend/resume etc.

Acceleration bring-up is incomplete due to NVIDIA not yet having
provided FW images for me to use, though command submission and copy
engines are functional already.
