It is still on my TODO list for revisiting, but I had other work on
patches taking me longer than originally expected. I now moved this
patch revisiting to the top of my TODO list; so, I will certainly look
into this today. So far, I have not set up an arm64 build on my local
machine and have not used tuxbuild (which should simplify all this
setup)---the typical challenges for a "part-time kernel
contributor/janitor"...

Arnd, I will certainly let you know by this evening (European time
zone) how far I got. If that is already too late, it is also perfectly
fine if this goes in 5.21 instead, but I will try my best to make it
5.20 material.

Thanks for the patience so far.


Best regards,

Lukas
