  perf powerpc: Fix build-test failure (2016-09-08 13:44:07 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Add branch stack / basic block info to 'perf annotate --stdio', where for
  each branch, we add an asm comment after the instruction with information on
  how often it was taken and predicted. See example with color output at:

    http://vger.kernel.org/~acme/perf/annotate_basic_blocks.png

  (Peter Zijlstra)

- Only open an evsel in CPUs in its cpu map, fixing some use cases in
  systems with multiple PMUs with different CPU maps (Mark Rutland)

- Fix handling of huge TLB maps, recognizing it as anonymous (Wang Nan)

Infrastructure:

- Remove the symbol filtering code, i.e. the callbacks passed to all functions
  that could end up loading a DSO symtab, simplifying the code, eventually
  allowing what we should have had since day one: removing the 'map' parameter
  from dso__load() functions (Arnaldo Carvalho de Melo)

Arch specific build fixes:

- Fix detached tarball build on powerpc, where we were still accessing a
  file outside tools/ (Ravi Bangoria)
