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.

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.

done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we

"This is preparation to solving the problems you've mentioned in the

done
as a for bulk search-and-replace.
After that, the kernel is ready to apply the patch to unify
{de,}mangle_poll(), and then get rid of kernel-side POLL... uses
entirely, and we should be all done with that stuff.
Basically, that's what you suggested wrt KPOLL..., except that we can
use EPOLL... instead - they already are arch-independent (and equal to
what is currently kernel-side POLL...).
After the preparations (in this series) switch to returning EPOLL...
from ->poll() instances is completely mechanical and kernel-side
POLL... can go away. The last step (killing kernel-side POLL... and
unifying {de,}mangle_poll() has to be done after the
search-and-replace job, since we need userland-side POLL... for
unified {de,}mangle_poll(), thus the cherry-pick at the last step.
After that we will have:
- POLL{IN,OUT,...} *not* in __poll_t, so any stray instances of
->poll() still using those will be caught by sparse.
- eventpoll.c and select.c warning-free wrt __poll_t

59f47eff03 ("powerpc/pci: Use of_irq_parse_and_map_pci() helper")
replaced of_irq_parse_pci() + irq_create_of_mapping() with
of_irq_parse_and_map_pci(), but neglected to capture the virq
returned by irq_create_of_mapping(), so virq remained zero, which
caused INTx configuration to fail.
Save the virq value returned by of_irq_parse_and_map_pci() and correct
the virq declaration to match the of_irq_parse_and_map_pci() signature.
