Jonathan Corbet 102caec107 docs: Take a little noise out of the build process
Sphinx 3.0 works at this point (albeit slowly) so stop scaring people
with a loud warning.  We also don't need to babble about CJK support in the
LaTeX build.

Akira Yokosawa 0afd4df0d1 docs: pdfdocs: Prevent column squeezing by tabulary
Setting a reasonable width to \tymin prevents column squeezing
by tabulary.
Width of 20em works well in almost all the tables still in the
ascii-art format.

Excerpt from tabulary package documentation at [1]:

    To stop very narrow columns being too 'squeezed' by this process
    any columns that are narrower than \tymin are set to their natural
    width.

[1]: https://mirrors.ctan.org/macros/latex/contrib/tabulary/tabulary.pdf

Note: Sphinx has its own default value of \tymin set in
sphinxlatextables.sty (Sphinx 4.0.2) and sphinxmulticell.sty
(Sphinx 2.4.4) as follows:

    \setlength{\tymin}{3\fontcharwd\font`0 }

, which is not sufficient for kernel-doc.

Tested against Sphinx versions 2.4.4 and 4.0.2.

Akira Yokosawa f7ebe6b769 docs: Activate exCJK only in CJK chapters
Activating xeCJK in English and Italian-translation documents
results in sub-optimal typesetting with wide-looking apostrophes
and quotation marks.

The xeCJK package provides macros for enabling and disabling its
effect in the middle of a document, namely \makexeCJKactive and
\makexeCJKinactive.

So the goal of this change is to activate xeCJK in the relevant
chapters in translations.

To do this:

    o Define custom macros in the preamble depending on the
      availability of the "Noto Sans CJK" font so that those
      macros can be used regardless of the use of xeCJK package.

    o Patch \sphinxtableofcontents so that xeCJK is inactivated
      after table of contents.

    o Embed those custom macros in each language's index.rst file
      as a ".. raw:: latex" construct.

Note: A CJK chapter needs \kerneldocCJKon in front of its chapter
heading, while a non-CJK chapter should have \kerneldocCJKoff
below its chapter heading.

This is to make sure the CJK font is available to CJK chapter's
heading and ending page's footer.

Tested against Sphinx versions 2.4.4 and 4.0.2.

Mauro Carvalho Chehab 3b4c963243 docs: conf.py: adjust the LaTeX document output
Changeset f546ff0c0c ("Move our minimum Sphinx version to 1.7")
cleaned up some compatibility issues with previous Sphinx
versions, but it also dropped the PDF margin sets.

Without that, the media documentation won't build fine, as
the margins are too wide to display texts with monospaced
fonts.

While here, align the  "latex_elements = {" values, and add
a few other sphinxsetup configs in order to allow Sphinx to
wrap long lines on literal blocks.

Mauro Carvalho Chehab 4658b0eb94 docs: conf.py: avoid thousands of duplicate label warning on Sphinx
The autosectionlabel extension is nice, as it allows to refer to
a section by its name without requiring any extra tag to create
a reference name.

However, on its default, it has two serious problems:

1) the namespace is global. So, two files with different
   "introduction" section would create a label with the
   same name. This is easily solvable by forcing the extension
   to prepend the file name with:

	autosectionlabel_prefix_document = True

2) It doesn't work hierarchically. So, if there are two level 1
   sessions (let's say, one labeled "open" and another one "ioctl")
   and both have a level 2 "synopsis" label, both section 2 will
   have the same identical name.

   Currently, there's no way to tell Sphinx to create an
   hierarchical reference like:

		open / synopsis
		ioctl / synopsis

  This causes around 800 warnings. So, the fix should be to
  not let autosectionlabel to produce references for anything
  that it is not at a chapter level within any doc, with:

	autosectionlabel_maxdepth = 2

Kees Cook aa20485528 doc-rst: Programmatically render MAINTAINERS into ReST
In order to have the MAINTAINERS file visible in the rendered ReST
output, this makes some small changes to the existing MAINTAINERS file
to allow for better machine processing, and adds a new Sphinx directive
"maintainers-include" to perform the rendering.

Features include:
- Per-subsystem reference links: subsystem maintainer entries can be
  trivially linked to both internally and external. For example:
  https://www.kernel.org/doc/html/latest/process/maintainers.html#secure-computing

- Internally referenced .rst files are linked so they can be followed
  when browsing the resulting rendering. This allows, for example, the
  future addition of maintainer profiles to be automatically linked.

- Field name expansion: instead of the short fields (e.g. "M", "F",
  "K"), use the indicated inline "full names" for the fields (which are
  marked with "*"s in MAINTAINERS) so that a rendered subsystem entry
  is more human readable. Email lists are additionally comma-separated.
  For example:

Darrick J. Wong 44ba0bb4f2 docs: improve readability for people with poorer eyesight
My eyesight is not in good shape, which means that I have difficulty
reading the online Linux documentation.  Specifically, body text is
oddly small compared to list items and the contrast of various text
elements is too low for me to be able to see easily.

Therefore, alter the HTML theme overrides to make the text larger and
increase the contrast for better visibility, and trust the typeface
choices of the reader's browser.

For the PDF output, increase the text size, use a sans-serif typeface
for sans-serif text, and use a serif typeface for "roman" serif text.

Jonathan Corbet 2a7c7cba38 docs: Remove "could not extract kernel version" warning
This warning will happen for every normal kernel docs build and doesn't
carry any useful information.  Should anybody actually depend on this
"version" variable (which isn't clear to me), the "unknown version" value
will be clue enough.

Mauro Carvalho Chehab 54d6d73f50 docs-rst: don't require adjustbox anymore
Only the media PDF book was requiring adjustbox, in order to
scale big tables. That worked pretty good with Sphinx versions
1.4 and 1.5, but Spinx 1.6 changed the way tables are produced,
by introducing some weird macros before tabulary.
That causes adjustbox to fail. So, it can't be used anymore,
and its usage was removed from the media book.

So, let's remove it from conf.py and sphinx-pre-install.

Mauro Carvalho Chehab 9fdcd6afd8 docs-rst: conf.py: only setup notice box colors if Sphinx < 1.6
Sphinx 1.5 added a new way to change backward colors for note
boxes, but kept backward compatibility with 1.4. On Sphinx 1.6,
the old way stopped working, in favor of a new less hackish
way.

Unfortunately, this is currently too buggy to be used, and
the old way doesn't work anymore. So, we have no option but
to stick with boring notice boxes.

One example of such bug is the notice that it is inside
struct v4l2_plane, at the "bytesused" field.

At least, add a notice about how to use, as maybe some day
the bug will vanish.

Mauro Carvalho Chehab 646056ec3b docs-rst: fix verbatim font size on tables
On Sphinx 1.6, fancy boxes are used for verbatim. The sphinx.sty
sets verbatim font is always \small. That causes a problem
inside tables that use smaller fonts, as it can be too big for
the box.

Mauro Carvalho Chehab 5148e6ab76 docs-rst: pdf: use same vertical margin on all Sphinx versions
Currently, on Sphinx up to version 1.4, pdf output uses a vertical
margin of 1 inch. For upper versions, it uses a margin of 0.5 inches.

That causes both page headers and footers to be very close to the margin
of the sheet. Not all printers support writing like that.

Also, there's no reason why the layout for newer versions would be
different than for previous ones.

So, standardize it, by always setting to 1 inch.
