Merge tag 'perf-urgent-for-mingo-4.19-20181005' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

- Fix the build on Clear Linux, coping with redundant declarations of
  function prototypes in python3 header files by adding
  -Wno-redundant-decls to build with PYTHON=python3 (Arnaldo Carvalho de Melo)

- Fixes for processing inline frames in backtraces using DWARF based
  unwinding (Milian Wolff)

- Cope with bad DWARF info for function names for inline frames,not
  trying to demangle this symbol. Problem reported with rust but
  reproduced as well with C++. Problem reported to the libbpf
  maintainers (Milian Wolff)

- Fix python export to postgresql and sqlite code (Adrian Hunter)
