It's based on drm-tip, otherwise, Intel CI wouldn't be able to apply the
series. drm-tip has that Etnaviv fix (commit 61ee19dedb8d "drm/etnaviv:
Protect the scheduler's pending list with its lock"), which drm-misc-
next doesn't have yet.

I believe I can apply the series to drm-misc-next and solve the
conflicts in drm-tip with `dim rebuild-tip`.

@drm-misc maintainers, would it be an issue if I apply this series to
drm-misc-next and solve the conflicts?
