[ Upstream commit 1f64cfdebfe0494264271e8d7a3a47faf5f58ec7 ]
Integers are not converted to floats during division in Python 2 which
results in incorrect IPC values. Fix by switching to new division
behavior.
Fixes: a483e64c0b62e93a ("perf scripting python: intel-pt-events.py: Add --insn-trace and --src-trace")
