Westmere I still hold off because the oprofile user land
doesn't have the correct event list yet.

BTW I was thinking in this case to only add the model
numbers to the user code and just let it handle arch_perfmon
from the kernel.

This should work currently fine and avoid the problem
that you need to update user land and kernel in parallel
for a new cpu type.

Yes would make sense. I'll ask around if there is a consolidated
list somewhere that could be used as a base.
