Aha.

So what do you need those INTEL_FAM6* defines for?

I see peci_cpu_device_ids[] which are used to match the CPU so at least
that thing must be loading on x86 hardware... reading your 0th message,
it sounds like that peci-cpu thing is loaded on an x86 CPU and it then
exposes those interfaces which a PECI controller accesses.

And then I see in init_core_mask() the single usage of INTEL_FAM6* and
that drivers/hwmon/peci/cputemp.c is a CPU temp monitoring client so
that thing probably runs on x86 too.

Or?

If it does, then you don't need the code move.

But it looks like I'm missing something...
