So once upon a time I set out to fix the problem reported by Tobin wherein
a literal block within a kerneldoc comment would be corrupted in
processing. On the way, though, I got annoyed at the way I have to learn
how kernel-doc works from the beginning every time I tear into it.
As a result, seven of the following eight patches just get rid of some dead
code and reorganize the rest - mostly turning the 500-line process_file()
function into something a bit more rational. Sphinx output is unchanged
after these are applied. Then, at the end, there's a tweak to stop messing
with literal blocks.
If anybody was unaware that I've not done any serious Perl since the
1990's, they will certainly understand that fact now.
Add the SPDX header while I'm in the neighborhood. The source itself just
says "GNU General Public License", but it also refers people to the COPYING
file for further information. Since COPYING says 2.0-only, that is what I
have put into the header.

It can be useful to put code snippets into kerneldoc comments; that can be
done with the "::" operator at the end of a line like this::
if (desperate)
run_in_circles();
The ".. code-block::" directive can also be used to this end. kernel-doc
currently fails to understand these literal blocks and applies its normal
markup to them, which is then treated as literal by sphinx. The result is
unsightly markup instead of a useful code snippet.
Apply a hack to the output code to recognize literal blocks and avoid
performing any special markup on them. It's ugly, but that means it fits
in well with the rest of the script.

The $in_purpose variable was a hidden substate of STATE_FIELD; get rid of

I found the layout confusing with multiple introductions to what
kernel-doc is and how to use it.
I made the following changes:
- Moved the 'Including kernel-doc comments' section to the end of
the document -- we should explain what it *is* before we explain
how to integrate it.
- Moved the 'Recommendations' subsection to the top. We want people
to know what to document before telling them how to do it.
- Rewrite the 'Writing kernel-doc comments' section, integrating
the 'Recommendations' subsection and a paragraph from 'How to format
kernel-doc comments'.
- Remove the paragraph about the kernel-doc script; we're supposed to
be teaching people how to use punctuation to write pretty documentation,
not documenting the build tooling.
- Split the 'Parameters and member arguments' section into 'Function
parameters' and 'Members'. Structure members are not commonly
referred to as arguments.
- Integrate the 'private:' and 'public:' tag descriptions into the
'Members' section.
- Move the 'In-line member documentation comments' subsection up to be
with the 'Members' section.

- eventpoll.c and select.c warning-free wrt __poll_t
- no more kernel-side definitions of POLL... - userland ones are
