Because at this time there are no vendor other than Intel that uses
thermal codes here. I don't know much about AMD, whether there are
any plan to implement AMD specific thermal codes or not, and why they
have to make such specific thing here in future (patent?).

You can pull out "codes may not be shared" from therm_throt.c and
put it again into mce_intel.c (that was mce_intel_64.c). But I
believe it is not needed now, until another code is available.
Or you can rename therm_throt.c to thermal_intel.c or so for a while.

(BTW, now CONFIG_X86_MCE_INTEL enables both of cmci and thermal,
are there possible option to disable thermal while cmci is on?)
