    Merge tag 'perf-core-for-mingo' 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:
    
      - Use PERF_RECORD_SWITCH when available in intel-pt, instead of
        "sched:sched_switch" events, enabling an unprivileged user to trace
        multi-threaded or multi-process workloads. (Adrian Hunter)
    
      - Always use non inlined file name for 'srcfile' sort key. (Andi Kleen)
    
      - Quieten failed to read counter message, helps in systems without
        backend-stalled-cycles. (Andi Kleen)
    
    Infrastructure changes:
    
      - Add a 'perf test' entry for decoding of new x86 instructions. (Adrian Hunter)
    
      - Add new instructions (sha, clflushopt, clwb, pcommit, rdpkru, wrpkru, xsavec,
        xsaves, xrstors) to the x86 instruction decoder. (Adrian Hunter)
    
      - Add a build test to warn when source code drifts happen for the
        instruction decoder files in the kernel and in tools/perf. (Adrian Hunter)
    
      - Copy linux/filter.h to tools/include. (He Kuang)
    
      - Support function __get_dynamic_array_len in libtraceevent. (He Kuanguuu)
    
      - Tracing path finding/mounting/error reporting refactorings. (Jiri Olsa)
    
      - Store CPU socket and core IDs in perf.data. (Kan Liang)
    
      - Reorganize add/del probe insertion routines in 'perf probe'. (Namhyung Kim, Wang Nan)
