The mcelog code just looks at model specific fields in MCi_STATUS
and MCi_MISC. We could move it to the kernel - but I don't see
much value in doing so. In this case all the information we need
is carried in status/misc - so as long as we keep all of those
bits (and the cpu family/model) we can safely decode/analyze later.
