[GIT PULL 0/5] perf/urgent hists hierarchy fixes

[Arnaldo Carvalho de Melo <acme@kernel.org>]

Hi Ingo,

	Please consider pulling these 'perf report/top --hierarchy' fixes into
perf/urgent, they don't fix segfaults, just some oddities in scrolling, etc.

	If you think it is too late in the 4.9-rc window, then please pull it
instead into perf/core, I did the build/test/container tests for both branches.

Thanks,

- Arnaldo
