Hi Chris,
I lit up the code in GENERIC in 886164895f — so that’s my fault :)
(any info about the thunderbolt devices would be appreciated!). obiwac@ asked
that I back it out, so I’ll take care of that now since it’s on my mind.
Thanks!

PS The thunderbolt(4) device implementation is incomplete: it was based on work
done by hselasky@ before he passed away back in 2023. I have a TODO item to
look at trying and get it working (enough) to have functional Thunderbolt/USB4
stack for storage purposes, but it’s way down my TODO list. tl;dr: I’m trying
to get a partially functional Mac x86 port before Apple nukes Intel support
from macOS.
