      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:
      
      New features:
      
        - Introduce PERF_RECORD_SWITCH(_CPU_WIDE) and use it in 'record' to
          ask for context switches, allowing non priviledged tasks to know
          when they are switched in and out, which wasn't possible with
          the other context switch tracepoint and software events, see the
          patch description for a comprehensive justification (Adrian Hunter)
      
        - Stop collecting /proc/kallsyms in perf.data files, saving about
          4.5MB on a typical x86-64 system, use the the symbol resolution
          routines used in all the other tools (report, top, etc) now that
          we can ask libtraceevent to use perf's symbol resolution code.
          (Arnaldo Carvalho de Melo)
      
      User visible fixes:
      
        - Expose perf's symbol resolver to libtraceevent, so that its plugins can
          resolve tracepoint fields to kernel functions, like the 'function' field
          in the "timer:hrtimer_start tracepoint" (Arnaldo Carvalho de Melo)
      
      Infrastructure changes:
      
        - Map propagation of thread and cpu maps improvements, prep work for
          'perf stat' new features (Jiri Olsa)
