perf report: Allow limiting the number of entries to print in callchains
Works by adding a third parameter to the '-g' argument, after the graph type and minimum percentage, for example: [root@doppio linux-2.6-tip]# perf report -g fractal,0.5,2 Will show only the first two symbols where at least 0.5% of the samples took place. All the other symbols that don't fall outside these constraints will be put together in the last entry, prefixed with "[...]" and the total percentage for them.
