Linux 4.20 rc7

ell, that's more like it.

This is a *tiny* rc7, just how I like it. Maybe it's because everybody
is too busy prepping for the holidays, and maybe it's because we
simply are doing well. Regardless, it's been a quiet week, and I hope
the trend continues.

The patch looks pretty small too, although it's skewed by a couple of
bigger fixes (re-apply i915 workarounds after reset, and dm zoned bio
completion fix). Other than that it's mainly all pretty small, and
spread out (usual bulk of drivers, but some arch updates, filesystem
fixes, core fixes, test updates..)

The plan remains the same: if everything continues normally, I'll
release 4.20 just before christmas, and then just have a more
leisurely merge window than normal. I already have a few early pull
requests, and I continue to encourage people to take that approach,
instead of sending things in during the holiday season.
