And after reading the next patch I still can't see that 71 is a
broadwell, because the next patch merily adds haswell names to the
numbers. Neither of the following patches has the magic 71
incorporated. The only model number related to broadwell is 61 in
patch 3/5.

Try again when you figured yourself out what number means what and why
71 is bogus.
