Merge branch 'drm-fixes-5.0' of git://people.freedesktop.org/~agd5f/linux into drm-fixes
A bit bigger than normal for this week due to fixes for some long
standing display issues that are bound for stable. These changes would
be going to stable anyway, so I figured it was better via 5.0 than 5.1.
- Several display fixes
- Fix PX systems due to core changes in runtime pm
- Disable bulk moves. They are fixed in 5.1, but fix is too invasive for 5.0
