Merge tag 'perf-core-for-mingo-20161024' 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:

New features:

- Dynamicly change verbosity level by pressing 'V' in the 'perf top/report'
  hists TUI browser (Alexis Berlemont)

- Implement 'perf trace --delay' in the same fashion as in 'perf record --delay',
  to skip sampling workload initialization events (Alexis Berlemont)

- Make vendor named events case insensitive in 'perf list', i.e.
  'perf list LONGEST_LAT' works just the same as  'perf list longest_lat' (Andi Kleen)

- Show instruction bytes and lenght in 'perf script' for Intel PT and BTS (Andi Kleen, Adrian Hunter)

   E.g:

    % perf record -e intel_pt// foo
    % perf script --itrace=i0ns -F ip,insn,insnlen
     ffffffff8101232f ilen: 5 insn: 0f 1f 44 00 00
     ffffffff81012334 ilen: 1 insn: 5b
     ffffffff81012335 ilen: 1 insn: 5d
     ffffffff81012336 ilen: 1 insn: c3
     ffffffff810123e3 ilen: 1 insn: 5b
     ffffffff810123e4 ilen: 2 insn: 41 5c
     ffffffff810123e6 ilen: 1 insn: 5d
     ffffffff810123e7 ilen: 1 insn: c3
     ffffffff810124a6 ilen: 2 insn: 31 c0
     ffffffff810124a8 ilen: 9 insn: 41 83 bc 24 a8 01 00 00 01
     ffffffff810124b1 ilen: 2 insn: 75 87

- Allow enabling the perf_event_attr.branch_type attribute member: (Andi Kleen)

  perf record -e sched:sched_switch,cpu/cpu-cycles,branch_type=any/ ...

- Add unwinding support for jitdump (Stefano Sanfilippo)

Fixes:

- Use raw_syscall:sys_enter timestamp in 'perf trace' (Arnaldo Carvalho de Melo)

Infrastructure:

- Allow jitdump to be built without libdwarf (Maciej Debski)

- Sync x86's syscall table tools/ copy (Arnaldo Carvalho de Melo)

- Fixes to avoid calling die() in library fuctions already propagating other
  errors (Arnaldo Carvalho de Melo)

- Improvements to allow libtraceevent to be properly installed in distro
  packages (Jiri Olsa)

- Removing coresight miscellaneous debug output (Mathieu Poirier)

- Cache align the 'perf bench futex' worker struct (Sebastian Andrzej Siewior)

Documentation:

- Minor improvements on the documentation of event parameters (Andi Kleen)

- Add jitdump format specification document (Stephane Eranian)

Spelling fixes:

- Fix typo "No enough" to "Not enough" (Alexander Alemayhu)
