COPYING: create a new file with points to the Kernel license files

With the addition of SPDX patchset, the contents of COPYING file
is now duplicated at two other files under LICENSE:
LICENSES/preferred/GPL-2.0
LICENSES/exceptions/Linux-syscall-note

It is easy to check that the contents of the licence written on
those files are identical with COPYING using:

$ diff -upr COPYING LICENSES/preferred/GPL-2.0
$ diff -upr COPYING LICENSES/exceptions/Linux-syscall-note|less

Also, a new file was added, with describes how SPDX should work at
the Kernel source files:
Documentation/process/license-rules.rst

Instead fo having it copying the contents of two files, and not
even mentioning the third one, replace it by a file whose content
points to the other tree files, preserving the Kernel's license.

Adjust license-rules.rst accordingly.

Please notice that this file preserves the Kernel license as
is, without any changes.

It's not full disclosure, it's not coordinated disclosure,
and it's not "no disclosure".  It's more like just "timely

I changed a bit of the wording in here, but mostly to remove the word
"disclosure" since it seems to mean very specific things to people
that we do not mean here.

Documentation: rapidio: move sysfs interface to ABI

Right now, the description of the rapidio sysfs interfaces is in
Documentation/rapidio/sysfs.txt. Since these are a part of the ABI, they
should be in Documentation/ABI along with the rest.

Merge branch 'kerneldoc2' into docs-next

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.

docs: Add an SPDX header to kernel-doc

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.

docs: kernel-doc: Don't mangle literal code blocks in comments

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.
