  perf trace: Provide a better explanation when mmap fails (2014-12-11 18:04:10 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Mark events as (x86 only) in help output for 'perf kvm stat live" (Alexander Yarygin)

- Provide a better explanation when mmap fails in 'trace' (Arnaldo Carvalho de Melo)

- Add --buildid-dir option to set cache directory, i.e. use:

      $ perf --buildid-dir /path/to/dir tool --tool-options

  (Jiri Olsa)

- Fix memcpy/memset 'perf bench' output (Rabin Vicent)

- Fix 'perf test' attr tests size values to cope with machine state on
  interrupt ABI changes (Jiri Olsa)

- Fixup callchain type parameter handling error message (Kan Liang)

Infrastructure/cleanups:

- calloc/xcalloc: Fix argument order (Arjun Sreedharan)

- Move filename__read_int from tools/perf/ to tools/lib, add sysctl__read_int
  there and use it in place of ad-hoc copies (Arnaldo Carvalho de Melo)

- Use single strcmp call instead of two (Jiri Olsa)

- Remove extra debugdir variables in 'perf buildid-cache' (Jiri Olsa)

- Fix -a segfault related to kcore handling in 'perf buildid-cache' (Jiri Olsa)

- Move cpumode resolve code to add_callchain_ip (Kan Liang)

- Merge memset into memcpy 'perf bench' (Rabin Vincent)

- Change print format from %lu to %PRIu64 in the hists browser (Tom Huynh)
