Subject: [PATCH 08/22] perf powerpc: Support CPU ID matching for Powerpc

From: Arnaldo Carvalho de Melo <[email-masked]>
Date: Mon, 3 Oct 2016 23:37:07 -0300

From: Sukadev Bhattiprolu <[email-masked]>

Implement code that returns the generic CPU ID string for Powerpc.  This
will be used to identify the specific table of PMU events to
parse/compare user specified events against.
