Subject: x86/cpu/intel: Introduce macros for Intel family numbers
From: Dave Hansen <dave@xxxxxxxx>
commit 970442c599b22ccd644ebfe94d1d303bf6f87c05 upstream.
Problem:
We have a boatload of open-coded family-6 model numbers. Half of
them have these model numbers in hex and the other half in
decimal. This makes grepping for them tons of fun, if you were
to try.
Solution:
Consolidate all the magic numbers. Put all the definitions in
one header.
The names here are closely derived from the comments describing
the models from arch/x86/events/intel/core.c. We could easily
make them shorter by doing things like s/SANDYBRIDGE/SNB/, but
they seemed fine even with the longer versions to me.
Do not take any of these names too literally, like "DESKTOP"
or "MOBILE". These are all colloquial names and not precise
descriptions of everywhere a given model will show up.
