Yes I have a patch series for that.  But it's not a new sort order but a
new command line option --culumate.  I don't think it should be a new
sort order since it affects only how it counts period value on each
sample not how samples are sorted/grouped.

It's about a year since I sent this series to list.  I'll work on it and
send it to the list soon.  But before that I have to re-read what's the
Frederic's concern - IIRC it's about consolidating code in perf report
that does similar things on branch stack.

Frederic, can you remember what was the problem?

Anyway, You can find the series and discussion on the link below:
