[Intel-xe] [PATCH 00/20] Sync DRM scheduler with upstream (with fixups)

[Rodrigo Vivi]

This work here is based on Matt's series:

https://patchwork.freedesktop.org/series/126029/

But updated to properly remove the old patches, cherry-pick the
new ones and adding fixup versions to the original xe patches.

The only modification is that for a cleaner cherry-pick, I
had to take couple more patches from drm-misc where
the DRM_SCHED_PRIORITY_UNSET was removed so, we are now
adding a local XE_SCHED_PRIORITY_UNSET for execlists.

After the clean-up rebases, with all the old patches removed,
the new ones added to the bottom and the fixup squashed to
the original, our drm-xe-next will look like this:

https://gitlab.freedesktop.org/rodrigovivi/drm-xe/-/commits/drm-sched-final-rebase

For reference, the branch with these reverts and fixups is
https://gitlab.freedesktop.org/rodrigovivi/drm-xe/-/tree/drm-sched-final-rebase-reverts-and-fixups

The git diff between these 2 branches is empty.

The git diff between any of these and the branch with Matt's
series applied is limited to the cases on drivers/gpu/drm/xe/xe_execlist.c

- DRM_SCHED_PRIORITY_UNSET
+ DRM_XE_SCHED_PRIORITY_UNSET

as explained above.

Steps to create fixup patches like these:
1. Get a final reference code (where you want to achieve).
2. Rebase removing the outdated patches, adding the new ones and fix the conflicts.
3. Create the fixup patches while solving the conflicts or later with the result
of the git range-diff
4. ensure that git range-diff between the brances are reasonable.
5. ensure empty git diff between the branches that you want.
6. send a series like this.
7. Now we wait for CI results.

Thanks,
Rodrigo.
