PDF build on Kernel 4.9-rc? returns an error with Sphinx 1.3.x
and Sphinx 1.4.x, when trying to solve some cross-references.
The solution is to redefine the \DURole macro.
However, this is redefined too late. Move such redefinition to
LaTeX preamble and bind it to just the Sphinx versions where the
error is known to be present.
Tested by building the documentation on interactive mode:
make PDFLATEX=xelatex -C Documentation/output/./latex

Set the default highlight language to "none", i.e. do not try to guess
the language and do automatic syntax highlighting on literal blocks.
Eyeballing around the generated documentation, we don't seem to actually
have a lot of literal blocks that would benefit from syntax
highlighting. The C code blocks we do have are typically very short, and
most of the literal blocks are things that shouldn't be highlighted (or,
do not have a pygments lexer). This seems to be true for literal blocks
both in the rst source files and in source code comments.
Not highlighting code is never wrong, but guessing the language wrong
almost invariably leads to silly or confusing highlighting.
At the time of writing, admin-guide/oops-tracing.rst and
admin-guide/ramoops.rst contain good examples of 1) a small C code
snippet not highlighted, 2) a hex dump highligted as who knows what, 3)
device tree block highlighted as C or maybe Python, 4) a terminal
interaction highlighted as code in some language, and finally, 5) some C
code snippets correctly identified as C. I think we're better off
disabling language guessing, and going by explicitly identified
languages for longer code blocks.
It is still possible to enable highlighting on an rst source file basis
using the highlight directive:
.. higlight:: language
and on a literal block basis using the code-block directive:
.. code-block:: language

thanks to Jani Nikula, Mauro Carvalho Chehab and Markus Heiser.
I've started a couple of new books: a driver API book (based on the old

formatting changes, but, I think, the results are worth it. The good news
is that most of our existing Documentation/*.txt files are *almost* in RST
format already; the amount of messing around required is minimal.
And, of course, there's the usual set of updates, typo fixes, and more.

Folders with a conf.py file, matching $(srctree)/Documentation/*/conf.py
can be build and distributed *stand-alone*. E.g. to compile only the
html of 'media' and 'gpu' folder use::
make SPHINXDIRS="media gpu" htmldocs
To use an additional sphinx-build configuration (*build-theme*) set the
name of the configuration file to SPHINX_CONF. E.g. to compile only the
html of 'media' with the *nit-picking* build use::
make SPHINXDIRS=media SPHINX_CONF=conf_nitpick.py htmldocs

Implements the reST flat-table directive.
The ``flat-table`` is a double-stage list similar to the ``list-table`` with
some additional features:
* column-span: with the role ``cspan`` a cell can be extended through
additional columns
* row-span: with the role ``rspan`` a cell can be extended through
additional rows
* auto span rightmost cell of a table row over the missing cells on the right
side of that table-row. With Option ``:fill-cells:`` this behavior can
changed from *auto span* to *auto fill*, which automaticly inserts (empty)
list tables
The *list tables* formats are double stage lists. Compared to the
ASCII-art they migth be less comfortable for readers of the
text-files. Their advantage is, that they are easy to create/modify
and that the diff of a modification is much more meaningfull, because
it is limited to the modified content.
The initial implementation was taken from the sphkerneldoc project [1]

Tell Sphinx where to find the extension, and pass on the kernel src tree
and kernel-doc paths to the extension.
With this, any .rst files under Documentation may contain the kernel-doc
rst directive to include kernel-doc documentation from any source file.
While building, it may be handy to pass kernel-doc extension
configuration on the command line. For example, 'make SPHINXOPTS="-D
kerneldoc_verbosity=0" htmldocs' silences all stderr output from
kernel-doc when the kernel-doc exit code is 0. (The stderr will be
logged unconditionally when the exit code is non-zero.)

Add basic configuration and makefile to build documentation from any
.rst files under Documentation using Sphinx. For starters, there's just
the placeholder index.rst.
At the top level Makefile, hook Sphinx documentation targets alongside
(but independent of) the DocBook toolchain, having both be run on the
various 'make *docs' targets.
All Sphinx processing is placed into Documentation/Makefile.sphinx. Both
that and the Documentation/DocBook/Makefile are now expected to handle
all the documentation targets, explicitly ignoring them if they're not
relevant for that particular toolchain. The changes to the existing
DocBook Makefile are kept minimal.
There is graceful handling of missing Sphinx and rst2pdf (which is
needed for pdf output) by checking for the tool and python module,
respectively, with informative messages to the user.
If the Read the Docs theme (sphinx_rtd_theme) is available, use it, but
otherwise gracefully fall back to the Sphinx default theme, with an
informative message to the user, and slightly less pretty HTML output.
Sphinx can now handle htmldocs, pdfdocs (if rst2pdf is available),
epubdocs and xmldocs targets. The output documents are written into per
output type subdirectories under Documentation/output.
Finally, you can pass options to sphinx-build using the SPHINXBUILD make
variable. For example, 'make SPHINXOPTS=-v htmldocs' for more verbose
output from Sphinx.
This is based on the original work by Jonathan Corbet, but he probably
wouldn't recognize this as his own anymore.
