As reported by Randy, running make htmldocs on a machine
without textlive now produce warnings:
$ make O=DOCS htmldocs
../Documentation/Makefile:70: warning: overriding recipe for target 'pdfdocs'
../Documentation/Makefile:61: warning: ignoring old recipe for target 'pdfdocs'
That's because the code has now two definitions for pdfdocs in
case $PDFLATEX command is not found. With the new script, such
special case is not needed anymore, as the script checks it.
Drop the special case. Even after dropping it, on a machine
without LaTeX, it will still produce an error as expected,
as running:
$ ./tools/docs/sphinx-build-wrapper pdfdocs
Error: pdflatex or latexmk required for PDF generation
does the check. After applying the patch we have:
$ make SPHINXDIRS=peci htmldocs
Using alabaster theme
Using Python kernel-doc
$ make SPHINXDIRS=peci pdfdocs
Error: pdflatex or latexmk required for PDF generation
make[2]: *** [Documentation/Makefile:64: pdfdocs] Error 1
make[1]: *** [/root/Makefile:1808: pdfdocs] Error 2
make: *** [Makefile:248: __sub-make] Error 2
Which is the expected behavior.

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.
