From 28c87b3dd5ed2ac90185b09bdc7233648d5d89b5 Mon Sep 17 00:00:00 2001
From: Cristian Stoica <cristian.stoica@nxp.com>
Date: Wed, 26 Oct 2016 09:14:28 +0300
Subject: [PATCH 059/104] fix some issues with parsing mpstat output
- mpstat with 'count' parameter will average the results for us on the
last line so we don't need to do this ourselves.
- set time format to ISO to avoid incorrect parsing of the header line
