4Subject: [PATCH 54/65] perf: Fix callchain hit bad cast on ascii display
5
6ipchain__fprintf_graph() casts the number of hits in a branch as an
7int, which means we lose its highests bits.
8
9This results in meaningless number of callchain hits in perf.data
10that have a high number of hits recorded, typically those that have
11callchain branches hits appearing more than INT_MAX. This happens
12easily as those are pondered by the event period.
