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