Merge tag 'perf-urgent-for-mingo-4.14-20171005' of git://git./linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fix from Arnaldo Carvalho de Melo:

- Two functions from different binaries can have the same start address. Thus,
  comparing only the start address in match_chain() leads to inconsistent
  callchains. Fix this by adding a check for DSOs as well (Ravi Bangoria)
