      Pull documentation format standardization from Jonathan Corbet:
       "This series converts a number of top-level documents to the RST format
        without incorporating them into the Sphinx tree. The hope is to bring
        some uniformity to kernel documentation and, perhaps more importantly,
        have our existing docs serve as an example of the desired formatting
        for those that will be added later.
      
        Mauro has gone through and fixed up a lot of top-level documentation
        files to make them conform to the RST format, but without moving or
        renaming them in any way. This will help when we incorporate the ones
        we want to keep into the Sphinx doctree, but the real purpose is to
        bring a bit of uniformity to our documentation and let the top-level
        docs serve as examples for those writing new ones"

      Linus Torvalds authored
      Pull random updates from Ted Ts'o:
       "Add wait_for_random_bytes() and get_random_*_wait() functions so that
        callers can more safely get random bytes if they can block until the
        CRNG is initialized.
      
        Also print a warning if get_random_*() is called before the CRNG is
        initialized. By default, only one single-line warning will be printed
        per boot. If CONFIG_WARN_ALL_UNSEEDED_RANDOM is defined, then a
        warning will be printed for each function which tries to get random
        bytes before the CRNG is initialized. This can get spammy for certain
        architecture types, so it is not enabled by default"

      Pull ->s_options removal from Al Viro:
       "Preparations for fsmount/fsopen stuff (coming next cycle). Everything
        gets moved to explicit ->show_options(), killing ->s_options off +
        some cosmetic bits around fs/namespace.c and friends. Basically, the
        stuff needed to work with fsmount series with minimum of conflicts
        with other work.
      
        It's not strictly required for this merge window, but it would reduce
        the PITA during the coming cycle, so it would be nice to have those
        bits and pieces out of the way"
