From 203f1f986a0d8504f0f843b42fa7f087d0c91a29 Mon Sep 17 00:00:00 2001
From: Todd E Brandt <todd.e.brandt@linux.intel.com>
Date: Wed, 14 Dec 2016 10:37:05 -0800
Subject: scripts: analyze_suspend.py: Update to upstream v4.3

- config file support added
- dev mode for monitoring kernel source calls and async kernel threads
- custom command support for executing a user cmd instead of suspend
- proc mode support for monitoring user processes with cpu exec data
- kprobe support for custom function tracing
- advanced callgraph support for function debug
- many bug fixes and formatting upgrades
