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

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

 into perf/urgent

Pull perf/core fixes from Arnaldo Carvalho de Melo:

Build fixes:

  - Create config.detected into OUTPUT directory, fixing parallel
    builds sharing the same source directory (Aaro Kiskinen)

  - Allow to specify custom linker command, fixing some MIPS64
    builds. (Aaro Kiskinen)

Infrastructure fixes:

  - Add missing break for PERF_RECORD_ITRACE_START, which caused those events
    samples to be parsed as well as PERF_RECORD_LOST_SAMPLES. ITRACE_START only
    appears when Intel PT or BTS are present, so  (Jiri Olsa)

  - Call the perf_session destructor when bailing out in the inject, kmem, report,
    kvm and mem tools (Taeung Song)
