Subject: [PATCH 0/7] Adding a proper workaround for fixing RTD3 issues with Nouveau

First three patches are removing ACPI workarounds which should have never
landed.

The last four are adding a workaround to nouveau which seem to help quite
a lot with the RTD3 issues with Nouveau, so let's discuss and get wider
testing of those and see if there is any fallout or laptops where the
issues don't get fixed.
