There is one thing we need to address (you might well be aware of).

Our Documentation/conf.py is not compatible for hrmldocs with
the combination sphinx_rtd_theme 1.0.0 and Sphinx >= 3.0.
This issue is the same as the one reported at:
    https://github.com/readthedocs/sphinx_rtd_theme/issues/1240
    "No stylesheet after upgrading to 1.0.0"

I tried the fix suggested there (html_css_files option),
and a stylesheet can be generated.
But the resulting html pages look quite different from the one
you see at https://www.kernel.org/doc/html/latest/ with the sans
font for text and distracting look of monospaced strings.

You can see a screenshot of such a page at
    https://fars.ee/nkkZ

I guess there should be some knobs of Sphinx for customizing
the style, but have not figured them out.

Thoughts?

        Thanks, Akira
