Merge branch 'linux-5.7' of git://github.com/skeggsb/linux into drm-next

A couple of misc fixes/workarounds for some issues that are causing a
lot of pain for people.

Of most interest are the PCI power management and GR init WARs, which
effect a rather significant number of laptop systems that are in use
today.
