Merge tag 'perf-urgent-for-mingo' of... 

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

 into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

 * The libaudit test was failing in some systems due to a unescaped newline, fix
   it so that the 'trace' tool can be built in such systems.

 * Fix installation of libexec components.

 * Add default handler for mmap2 events so that tools that don't explicitely
   define an MMAP2 handler don't crash, fix from David Ahern.

 * Fix to find line information for probe list, from Masami Hiramatsu.

 * Set child_pid after perf_evlist__prepare_workload(), fix from Namhyung Kim.

 * Fix infinite loop on invalid perf.data file, from Namhyung Kim.
