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

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

 into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

 * Don't install scripting files files when perl/python support is disabled.

 * Support ! in -e expressions in 'perf trace', to filter a list of syscalls.

 * Add --verbose and -o/--output options to 'perf trace'.

 * Introduce better formatting of syscall arguments in 'perf trace',
   including so far beautifiers for mmap, madvise, syscall return
   values.

 * Fixup jobserver setup in libtraceevent makefile.

 * Debug improvements from Adrian Hunter.

 * Try to increase the file descriptor limits on EMFILE, from Andi Kleen.

 * Remove unused force option in 'perf kvm', from David Ahern.

 * Make 'perf trace' command line arguments consistent with 'perf record',
   from David Ahern.

 * Fix correlation of samples coming after PERF_RECORD_EXIT event, from
   David Ahern.
