The branch built with no problems, and now I merged this into
devel. If that also builds fine, I will let it hit linux-next so we can
stabilize it for v4.20.

I applied the v8 to an immutable branch and pushed to kernelorg
so the build servers can churn it a bit, and if it works fine
then we can merge this into the devel branch and also set up
that as something other subsystems can pull in if they need it.

I'm really excited to merge this!
