Below is the list of build error/warning regressions/improvements in
v5.17-rc1[1] compared to v5.16[2].
Summarized:
- build errors: +17/-2
- build warnings: +23/-25
Note that there may be false regressions, as some logs are incomplete.
Still, they're build errors/warnings.
Happy fixing! ;-)
Thanks to the linux-next team for providing the build service.

I don't really see what's going on here:
#ifdef CONFIG_X86_64
return cpu_data(first_cpu_of_numa_node).apicid;

ah yes, UML.
I have a bunch of UML fixes that I have been hesitant to post.
This is one of them.
What do people think about this?

I also meant to reply that someone could just add
depends on !UML
for this device, like you are suggesting.
I'm fine with it either way.
