      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 the alternative with the most descriptive filename containing
          a vmlinux file for a given build-id, providing a better title line
          for tools such as 'annotate'. (Arnaldo Carvalho de Melo)
      
        - Remove help messages about previous right and left arrow keybidings, that
          were repurposed for horizontal scrolling. (Arnaldo Carvalho de Melo)
      
        - Inform how to reset the symbol filter in the hists browser. (top & report)
          (Arnaldo Carvalho de Melo)
      
        - Add 'm' key for context menu display in the hists browser, that became
          inacessible with the repurposing of the right arrow key for horizontal
          scrolling. (Namhyung Kim)
      
        - Use debug_frame for callchains if eh_frame is unusable. (Rabin Vicent)
      
      Build fixes:
      
        - Fix strict-aliasing breakage with gcc 4.4 in the READ_ONCE/WRITE_ONCE code
          adopted from the kernel tree, that builds with -fno-strict-aliasing while
          tools/perf/ uses -Wstrict-aliasing=3. (Jiri Olsa)
      
        - Fix unw_word_t pointer casts in code using libunwind for callchains,
          fixing the build in at least 32-bit MIPS systems. (Rabin Vicent)
      
        - Work around cross compile build problems related to fixdep. (Jiri Olsa)

      User visible changes:
      
        - Adding a field via 'perf report -F' that already is enabled makes
          the tool get stuck in a loop, fix it. (Jiri Olsa)
      
      Infrastructure changes:
      
        - Support PERF_RECORD_SWITCH in the python binding. (Arnaldo Carvalho de Melo)
      
        - Fix handling read() result using a signed variable, found with Coccinelle.

      To test it check tools/perf/python/twatch.py, after following the
      instructions there to enable context_switch, output looks like:
