Merge tag 'perf-core-for-mingo-4.11-20170209' of... 

Merge tag 'perf-core-for-mingo-4.11-20170209' 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:

User visible changes:

 - Add support for parsing Intel uncore vendor event files and add uncore
   vendor events for the Intel server processors (Haswell, Broadwell,
   IvyBridge), Xeon Phi (Knights Landing) and Broadwell DE (Andi Kleen)

 - Support --symfs in 'perf probe' (Uwe Kleine-König)

 - Add support for generating bpf prologue on the aarch64 architecture (He Kuang)

 - Show proper hint when SDT event not yet in place via 'perf probe' (Ravi Bangoria)

 - Take into account symfs setting when reading file build ID (Victor Kamensky)

Infrastructure changes:

 - Map gcc7's '__attribute__ ((fallthrough))', that warns when code
   associated to case blocks in switches continue into the next case entry,
   to '__falltrough' and use it where warned by gcc, tested on Fedora Rawhide
   (Arnaldo Carvalho de Melo)

 - Fix buffer sizes used with snprintf that could lead to truncation,
   another warning introduced in gcc7 (Arnaldo Carvalho de Melo)

 - Robustify do_generate_dynamic_list_file in libtraceevent (David Carrillo-Cisneros)

 - Use zfree() in more places (Taeung Song)
