That's too fine-grained IMO and look at the path we'd get then:

arch/x86/kernel/cpu/mce/cpu/intel.c
^^^ ^^^

which brings me to something we already talked about: the "kernel" part
of the arch/x86/ paths. See this thread:

https://lkml.kernel.org/r/20140114185802.GB29871@pd.tnic

from 2014. We practically agreed there that "kernel/" is redundant as it
all is kernel. So maybe we should start moving stuff up into arch/x86/
and then kill kernel/ eventually.

Yeah, I think the pile in mce/ is pretty succinct now. We can always
separate it more later, if it starts to hurt but right now it is ok,
IMO.
