  perf tests: Add is_printable_array test (2016-07-18 19:50:35 -0300)

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

User visible:

- Properly report when a function wildcard produces no matches in 'perf probe'
  (Masami Hiramatsu)

- Balance opening and reading events in 'perf stat', which could cause
  it to get stuck trying to close invalid file descriptors (Mark Rutland)

Infrastructure:

- Copy more headers from the kernel, this time for headers that
  were just including the contents of its kernel counterparts, should
  help resolving the problems with linux-next, where some uapi related
  patches seem to be breaking tools/object/ build.

  Some more combing will be done, but at least it is possible to build
  perf out of tree, via a detached tarball (make help | grep perf)
  without including kernel files in its MANIFEST (Arnaldo Carvalho de Melo)

- Fix smatch found errors that were not causing problems, but are
  mistakes nonetheless (Dan Carpenter)

- Fix string vs byte array resolving in the python script code (Jiri Olsa)
