Subject: perf/x86/uncore: Rename IvyTown to IvyBridge-EP
From: Peter Zijlstra <peterz@xxxxxxxxxxxxx>
Date: Tue Aug 12 09:15:25 CEST 2014

Keeping track of all the various CPU names is hard enough; adding extra
silly names for no reason is just not helping. If we know the base arch
name (IvyBridge) then we can do the client/server parts with the well
known {,EP,EX} postfixes, no need to remember endless amounts of
unrelated and pointless names for this.
