Subject: [PATCH 1/5] x86, intel: Introduce macros for Intel family numbers


From: Dave Hansen <dave.hansen@...ux.intel.com>

We have at least four long lists 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.

So, let's consolidate them.  Put all the definitions in one
header.  While people have been _pretty_ good at making sure to
hit all four places in the code when Intel puts out a new CPU, we
have not been perfect, and this should make it easier.

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.
