Merge tag 'perf-core-for-mingo-4.16-20180125' 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:

- Introduce a errno code to string facility to allow tools such as
  'perf trace' to support multi-arch perf.data decoding/beautifying,
  uses errno header files copied from the kernel, this allows
  removing the need for audit-libs in arches generating its syscall
  tables from the kernel sources, so far x86 and s/390 (Hendrik Brueckner)

- Intel-PT/BTS sample synthesizing fixes (Adrian Hunter)

- Intel vendor event JSON updates for the Broadwell, BroadwellDE,
  BroadwellX, Goldmont, Haswell, HaswellX, IvyBridge, IvyBridge, IvyTown,
  IvyTown, Silvermont, Skylake and SkylakeX architectures. (Andi Kleen)

- Use ui__error() to have --field error handling messages not to
  disappear due to TUI exit cleanup (Arnaldo Carvalho de Melo)

- Don't warn about unavailability of builtin clang in 'perf trace', just
  continue fallbacking to using the external toolchain (Arnaldo Carvalho de Melo)

- Move conditional O_CLOEXEC define to util.h to keep the build
  working on older distros where that is not available now that
  this define will be used in more source files (Arnaldo Carvalho de Melo)

- Using O_CLOEXEC in do_open() to avoid having too many open files when
  using 'perf script' from the 'perf report' TUI scripts browser (Wang YanQing)

- Add 'perf trace --print-sample' to help in debugging the printing
  of timestamp calculations, for instance (Arnaldo Carvalho de Melo)

- Do not print from time delta for interrupted syscall lines in 'perf
  trace' (those ending with '...') just print the total syscall duration
  at raw_syscalls:sys_exit time (Arnaldo Carvalho de Melo)

- Beautify FUTEX_BITSET_MATCH_ANY in the futex syscall in 'perf trace'
  (Arnaldo Carvalho de Melo)

- Display EXTRA features for 'make VF=1' build (Jiri Olsa)

- Add support for CoreSight trace decoding by making the perf tools
  use the external openCSD (Mathieu Poirier, Tor Jeremiassen)
