Merge tag 'perf-core-for-mingo-20160920' of... 

Merge tag 'perf-core-for-mingo-20160920' 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:

- Support event group view with hierarchy mode in 'perf top' and 'perf report'
  (Namhyung Kim)

  e.g.:

  $ perf record -e '{cycles,instructions}' make
  $ perf report --hierarchy --stdio
  ...
  #               Overhead  Command / Shared Object / Symbol
  # ......................  ..................................
  ...
      25.74%  27.18%        sh
         19.96%  24.14%        libc-2.24.so
            9.55%  14.64%        [.] __strcmp_sse2
            1.54%   0.00%        [.] __tfind
            1.07%   1.13%        [.] _int_malloc
            0.95%   0.00%        [.] __strchr_sse2
            0.89%   1.39%        [.] __tsearch
            0.76%   0.00%        [.] strlen

- Fix the dwarf regs table for x86_64, adding a missing % to the "%di"
  register, noticed with a failing 'perf test bpf' (Arnaldo Carvalho de Melo)

- Fix handling of mmap parameters in the 'perf trace' beautifier in
  architectures that don't have the same mappings as x86_64 (Wang Nan)

- Handle hugetbl mappings in older systems running new kernels (Wang Nan)

- Resolve 'call' operands in 'annotate', that when using /proc/kcore
  were appearing just as hexadecimal addresses, to function names
  (Arnaldo Carvalho de Melo)

- Fix width computation for srcline sort entry (Jiri Olsa)

- Do not ignore call instruction with indirect target in 'annotate'
  (Ravi Bangoria)

- Handle MADV_FREE in the madvise 'trace' beautifier (Wang Nan)

- Fix build of 'perf trace' mman beautifier in !x86_64 (Wang Nan)

Infrastructure changes:

- Add infrastructure for PMU specific configuration, allowing to pass
  config variables directly to the kernel PMU driver, prefixing those
  variables with a '@', part of a larger series to support Coresight (Mathieu Poirier)
