Please see below..

The struct map_symbol__folded() was called from hist_entry__folded()
and callchain_list__folded(). I just removed map_symbol__folded()
since it does not contain the info anymore and open coded it just for
the two callers. The real callers of these functions are not touched.

Here.

Thanks,
