  perf stat: Fallback to user only counters when perf_event_paranoid > 1 (2016-05-12 16:25:18 -0300)

----------------------------------------------------------------
perf/urgent fixes:

User visible:

- Fallback to usermode only counters when perf_event_paranoid > 1, which
  is the case now (Arnaldo Carvalho de Melo)

- Do not reassign parg after collapse_tree() in libtraceevent, which
  may cause tool crashes (Steven Rostedt)

Build fixes:

- Fix the build on Fedora Rawhide, where readdir_r() is deprecated and
  also wrt -Werror=unused-const-variable= + x86_32_regoffset_table on
  !x86_64 (Arnaldo Carvalho de Melo)

- Fix the build on Ubuntu 12.04.5, where dwarf_getlocations() isn't
  available, i.e. libdw-dev < 0.157 (Arnaldo Carvalho de Melo)

Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>

----------------------------------------------------------------
Arnaldo Carvalho de Melo (9):
      perf tools: Use readdir() instead of deprecated readdir_r()
      perf script: Use readdir() instead of deprecated readdir_r()
      perf thread_map: Use readdir() instead of deprecated readdir_r()
      perf tools: Use readdir() instead of deprecated readdir_r()
      perf dwarf: Guard !x86_64 definitions under #ifdef else clause
      perf probe: Check if dwarf_getlocations() is available
      perf evsel: Improve EPERM error handling in open_strerror()
      perf evsel: Handle EACCESS + perf_event_paranoid=2 in fallback()
      perf stat: Fallback to user only counters when perf_event_paranoid > 1
