Merge tag 'perf-core-for-mingo-4.15-20171023' of git://git.kernel.org/pub/scm/linux...

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

 - Update vendor events JSON metrics for Intel's Broadwell, Broadwell
   Server, Haswell, Haswell Server, IvyBridge, IvyTown, JakeTown, Sandy
   Bridge, Skylake and SkyLake Server (Andi Kleen)

 - Add vendor event file for Intel's Goldmont Plus V1 (Kan Liang)

 - Move perf_mmap methods from 'perf record' and evlist.c to a separate
   mmap.[ch] pair, to better separate things and pave the way for further
   work on multithreading tools (Arnaldo Carvalho de Melo)

 - Do not check ABI headers in a detached tarball build, as it the kernel
   headers from where we copied tools/include/ are by definition not
   available (Arnaldo Carvalho de Melo)

 - Make 'perf script' use fprintf() like printing, i.e. receiving a FILE
   pointer so that it gets consistent with other tools/ code and allows
   for printing to per-event files (Arnaldo Carvalho de Melo)

 - Error handling fixes (resource release on exit) for 'perf script'
   and 'perf kmem' (Christophe JAILLET)

 - Make some 'perf event attr' tests optional on virtual machines, where
   tested counters are not available (Jiri Olsa)
