[PATCH 28/35] perf script python: Add Python3 support to intel-pt-events.py

From: Arnaldo Carvalho de Melo
Date: Thu Mar 07 2019 - 12:46:48 EST


From: Tony Jones <tonyj@xxxxxxx>

Support both Python2 and Python3 in the intel-pt-events.py script

There may be differences in the ordering of output lines due to
differences in dictionary ordering etc. However the format within lines
should be unchanged.

The use of 'from __future__' implies the minimum supported Python2 version
is now v2.6
