Subject: [PATCH 06/20] perf diff: Removing the total_period argument from output code
From: Jiri Olsa <jolsa@...hat.com>
The total_period is available in struct hists data via the 'struct
hist_entry::hists' pointer. There's no need to carry it through the
output code path.
Removing 'struct perf_hpp::total_period' pointer, because it's no
longer needed.
