Akira Yokosawa 398f7abdcb docs: pdfdocs: Pull LaTeX preamble part out of conf.py
Quote from Jon's remark [1]:

    I do notice that Documentation/conf.py is getting large and
    unapproachable.  At some future point, it might be nice to pull
    all of the latex stuff out into a separate file where it won't
    scare people who stumble into it by accident.

Pull LaTeX preamble settings added since commit 3b4c963243 ("docs:
conf.py: adjust the LaTeX document output") out into
sphinx/kerneldoc-preamble.sty.

It will be copied to the build directory by the added
"latex_additional_files" setting in conf.py.

As a bonus, LaTeX/TeX code can be maintained without escaping backslashes.

To compensate the loss of change history in sphinx/kerneldoc-preamble.sty,
here is a list of changes made in conf.py:

  - f7ebe6b769 ("docs: Activate exCJK only in CJK chapters")
  - 0afd4df0d1 ("docs: pdfdocs: Prevent column squeezing by tabulary")
  - 659653c9e5 ("docs: pdfdocs: Refactor config for CJK document")
  - e291ff6f5a ("docs: pdfdocs: Add CJK-language-specific font settings")
  - 7eb368cc31 ("docs: pdfdocs: Choose Serif font as CJK mainfont if possible")
  - 35382965bd ("docs: pdfdocs: Preserve inter-phrase space in Korean translations")
  - 77abc2c230 ("docs: pdfdocs: One-half spacing for CJK translations")
  - 788d28a257 ("docs: pdfdocs: Permit AutoFakeSlant for CJK fonts")
  - 29ac982235 ("docs: pdfdocs: Teach xeCJK about character classes of quotation marks")
  - 7c5c18bdb6 ("docs: pdfdocs: Fix typo in CJK-language specific font settings")
  - aa872e0647 ("docs: pdfdocs: Adjust \headheight for fancyhdr")
  - 8716ef413a ("docs: pdfdocs: Tweak width params of TOC")
  - 66939df539 ("docs: pdfdocs: Switch default CJK font to KR variants")
  - 7b686a2ea1 ("docs: pdfdocs: Enable CJKspace in TOC for Korean titles")
  - 5d9158e3c7 ("docs/translations: Skip CJK contents if suitable fonts not found")
  - b774cc4631 ("docs: pdfdocs: Move CJK monospace font setting to main conf.py")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
