Fedora and openSUSE has started deploying "variable font" [1] format Noto CJK fonts [2, 3]. "CJK" here stands for "Chinese, Japanese, and Korean". Unfortunately, XeTeX/XeLaTeX doesn't understand those fonts for historical reasons and builds of translations.pdf end up in errors if such fonts are present on the build host. To help developers work around the issue, add a script to check the presence of "variable font" Noto CJK fonts and to emit suggestions. The script is invoked in the error path of "make pdfdocs" so that the suggestions are made only when a PDF build actually fails. The first suggestion is to denylist those "variable font" files by activating a per-user and command-local fontconfig setting. For further info and backgrounds, please refer to the header comment of scripts/check-variable-font.sh newly added in this commit.

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 reStructuredText 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.
