Subject: [PATCH] perf stat: update POWER9 metrics to utilize other metrics
Date:   Thu, 13 Aug 2020 17:21:55 -0500
Message-Id: <20200813222155.268183-1-pc@us.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

These changes take advantage of the new capability added in
merge commit 00e4db51259a5f936fec1424b884f029479d3981
"Allow using computed metrics in calculating other metrics".

The net is a simplification of the expressions for a handful
of metrics, but no functional change.
