I would say it was this one, without bisecting:

perf top: Reuse the 'report' hist_entry/hists classes
This actually fixes several problems we had in the old 'perf top':
1. Unresolved symbols not show, limitation that came from the old
"KernelTop" codebase, to solve it we would need to do changes
that would make sym_entry have most of the hist_entry fields.
2. It was using the number of samples, not the sum of sample->period.
And brings the --sort code that allows us to have all the views in
'perf report', for instance:
<SNIP>
--------------------------------------------------------------------------------
It ended up only honouring the zeroing logic for the annotation stuff.
Anyway, reviewing Namhyung proposed fix now.
