perf script python: add Python3 support to check-perf-trace.py
Support both Python 2 and Python 3 in the check-perf-trace.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 version of Python2 is now v2.6 Signed-off-by: Tony Jones <tonyj@suse.de> Cc: Tom Zanussi <tzanussi@gmail.com> Link: http://lkml.kernel.org/r/20190302011903.2416-4-tonyj@suse.de Signed-off-by: Seeteena Thoufeek <s1seetee@linux.vnet.ibm.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
