2017-04-20perf tools: Add signal.h to places using its definitionsArnaldo Carvalho de Melo

2016-08-23perf hists: Add support for header spanJiri Olsa
Add span argument for header callback function. The handling of this argument is completely in the hands of the callback. The only thing the caller ensures is it's zeroed on the beginning. Omitting span skipping in hierarchy headers and gtk code. The c2c code use this to span header lines based on the entries span configuration.

2013-08-07perf ui/gtk: Fix segmentation fault on perf_hpp__for_each_format loopNamhyung Kim
The commit 2b8bfa6bb8a7 ("perf tools: Centralize default columns init in perf_hpp__init") moves initialization of common overhead column to perf_hpp__init() but forgot about the gtk code. So the gtk code added the same column to the list twice causing infinite loop when iterating it by perf_hpp__for_each_format loop. When I run perf report --gtk, I can see following messages indefinitely.
