Changes from v1:
 * added acks from a few folks
 * Took the redundant "MODEL_" out of the macro names (Suggested
   by Borislav Petkov and acked by others)

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

If you are cc'd on this code, please check _your_ code vs. the
model list in "intel-family.h".  Please make sure you have all
the models listed that you intend to.

Also, rather than trickling these in via all the various
maintainers, should these just get pulled in to the x86 tree in
one go?

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.

These have all been compile-tested.  I also made a stab at
dumping .o files and looking for unexpected deltas when I was
just replacing magic numbers with equivalent macros.

World-record-attempt at cc list length follows.

So I've picked up this series and restructured it: I've created a single patch 
that creates intel-family.h and have put it into x86/urgent. This eliminated 
dependencies and allowed some of the patches to be queued in their natural trees, 
in particular the 7 perf patches.

Thanks,

	Ingo
