Sorry but the previous one was better: INTEL_FAM6_ATOM_SILVERMONT I can
find in the tree...

For ATOM_SILVERMONT I find different things:

INTEL_CPU_FAM6(ATOM_SILVERMONT
X86_CSTATES_MODEL(INTEL_FAM6_ATOM_SILVERMONT
ICPU(INTEL_FAM6_ATOM_SILVERMONT
...

so you guys need to sit down and agree on a single form of usage and
stick with it.

And I'd advise against the first one which cuts off the
INTEL_FAM6_ATOM_SILVERMONT and other defines.

Thx.
