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! ;-)

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?
Does it make sense to configure a UML kernel with a real device driver in the first place? Or should we just prevent enabling amdgpu for UML with a Kconfig dependency?

I don't really see what's going on here:
#ifdef CONFIG_X86_64 return cpu_data(first_cpu_of_numa_node).apicid; #else return first_cpu_of_numa_node; #endif
Ah, the actual failure causing this was not included:

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?
Does it make sense to configure a UML kernel with a real device driver in the first place? Or should we just prevent enabling amdgpu for UML with a Kconfig dependency?
Hi,
Your option IMO. I have seen both opinions given. 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.
thanks.
thanks.

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.
