This looks somewhat useful, although I was expecting more of a graphic presentation
of the tree structure. But that would cause trouble with the role of each subdirectory.
(and one can always use `tree` for that)

This patch adds a basic source map that describes the role of each top-level directory in the kernel source.

Patches should generally be inline as email text, not as attachments.
This is up to the maintainer to decide about...
and gmail is not good as maintaining whitespace in emails.
(I don't see any whitespace problems in the current patch.)

I get a warning when building with this patch applied:

Documentation/source-map.rst: WARNING: document isn't included in any toctree [toc.not_included]

Also, when I look at source-map.html with a web browser, no parts of
the source-map are shown. (tested with multiple browsers)

Thanks.
