      docs: sphinx/kfigure.py: Use rsvg-convert(1) for DOT -> PDF conversion · c9edbe1e
      Akira Yokosawa authored
      On openSUSE, dot(1) command does not support direct PDF output.
      On other distros, generated PDF images have unnecessarily wide margins,
      especially for small graphs.
      
      By using dot(1) for DOT -> SVG, then rsvg-convert(1) for SVG -> PDF,
      more optimal PDF images can be obtained, with the bonus of improved
      portability across various distros.
      
      Add rules in kfigure.py so that the above mentioned route is taken
      when rsvg-convert(1) is available.
      
      Note that rsvg-convert(1) is recommended by sphinx_pre_install.
      So it is most likely that existing systems for building pdfdocs have
      rsvg-convert(1) installed.
      
      Note:
          SVG features supported by rsvg-convert(1) vary depending on its
          version and distro config.
          For example, the one found on Ubuntu Bionic (version 2.40.20) does
          poor job in rendering some of SVG files drawn by Inkscape.
          SVG files generated by dot(1) are converted nicely even with such
          old versions of rsvg-convert.
      
          So this change does not affect the quality of such figures in any
          way.

      Pull ftrace fix from Steven Rostedt:
       "Fix s390 breakage from sorting mcount tables.
      
        The latest merge of the tracing tree sorts the mcount table at build
        time. But s390 appears to do things differently (like always) and
        replaces the sorted table back to the original unsorted one. As the
        ftrace algorithm depends on it being sorted, bad things happen when it
        is not, and s390 experienced those bad things.
      
        Add a new config to tell the boot if the mcount table is sorted or
        not, and allow s390 to opt out of it"

      ftrace: Fix assuming build time sort works for s390 · 6b9b6413
      Steven Rostedt (Google) authored
      To speed up the boot process, as mcount_loc needs to be sorted for ftrace
      to work properly, sorting it at build time is more efficient than boot up
      and can save milliseconds of time. Unfortunately, this change broke s390
      as it will modify the mcount_loc location after the sorting takes place
      and will put back the unsorted locations. Since the sorting is skipped at
      boot up if it is believed that it was sorted at run time, ftrace can crash
      as its algorithms are dependent on the list being sorted.
      
      Add a new config BUILDTIME_MCOUNT_SORT that is set when
      BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
      if sorting should take place at boot up.
