Subject: [ 13/73] perf/x86/intel: Add support for IvyBridge model 58 Uncore

3.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vince Weaver <vincent.weaver@...ne.edu>

commit 9a6bc14350b130427725f33e371e86212fa56c85 upstream.

According to Intel Vol3b 18.9, the IvyBridge model 58 uncore is
the same as that of SandyBridge.

I've done some simple tests and with this patch things seem to
work on my mac-mini.
