Pull documentation updates from Jonathan Corbet:
 "This has been another busy cycle for documentation, with a lot of
  build-system thrashing. That work should slow down from here on out.

   - The various scripts and tools for documentation were spread out in
     several directories; now they are (almost) all coalesced under
     tools/docs/. The holdout is the kernel-doc script, which cannot be
     easily moved without some further thought.

   - As the amount of Python code increases, we are accumulating modules
     that are imported by multiple programs. These modules have been
     pulled together under tools/lib/python/ -- at least, for
     documentation-related programs. There is other Python code in the
     tree that might eventually want to move toward this organization.

   - The Perl kernel-doc.pl script has been removed. It is no longer
     used by default, and nobody has missed it, least of all anybody who
     actually had to look at it.

   - The docs build was controlled by a complex mess of makefilese that
     few dared to touch. Mauro has moved that logic into a new program
     (tools/docs/sphinx-build-wrapper) that, with any luck at all, will
     be far easier to understand and maintain.

   - The get_feat.pl program, used to access information under
     Documentation/features/, has been rewritten in Python, bringing an
     end to the use of Perl in the docs subsystem.

   - The top-level README file has been reorganized into a more
     reader-friendly presentation.

   - A lot of Chinese translation additions

   - Typo fixes and documentation updates as usual"
