I've got a few other riscv kvm selftests cleanup patches locally queued.
I'll add another one which moves the prototype to include/riscv/processor.h
and include/aarch64/processor.h. Making guest_get_vcpuid() common (for
which I think I'm to blame) was premature and, as you point out, it should
have at least been named arch_guest_get_vcpuid(). I could do the rename
instead, but since I'm not sure if it'll ever get adopted outside riscv
and aarch64, I'll just move for now.

Thanks,
