I believe those patches, together with commit 3efadf028783 ("drm/me/gsc:
mei interrupt top half should be in irq disabled context") that is in
drm-xe-next, are enough for making PREEMPT_RT basic functionality work
on xe without problems.
There are still some issues specific to PREEMPT-RT, like on how to handle
vblank interrupt, but I do not believe it should be a blocker for merging the
series.
