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?
Regards, Felix
thanks.
