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.
