[PATCH v2 0/3] drm/xe/display: Fixes to make kexec work.

[Maarten Lankhorst]

Lets see if we can get away with performing a FLR as shutdown handler. It should work.
These are all the patches I have used when testing if I could kexec from Xe with a game
running  to a new kernel.

Tested with:
kexec --reuse-cmdline --initrd=initrd.img -f vmlinuz

I have tested about 4-5 times successive kexecs on my ADL-P,
while having a game actively running to keep the GPU loaded.

With this series xe kept running succesfully. After that
I accidentally rebooted, but I see no reason this wouldn't work
even more times.

Changes since previous version:
- s/r patches have been merged.
