Documentation: update numastat explanation

During recent patch discussion [1] it became apparent that the "other_node"
definition in the numastat documentation has always been different from actual
implementation. It was also noted that the stats can be innacurate on systems
with memoryless nodes.

This patch corrects the other_node definition (with minor tweaks to two more
definitions), adds a note about memoryless nodes and also two introductory
paragraphs to the numastat documentation.

Merge branch 'mauro' into docs-next

Mauro says:

This is the second part of a series I wrote sometime ago where I manually
convert lots of files to be properly parsed by Sphinx as ReST files.

As it touches on lot of stuff, this series is based on today's linux-next,
at tag next-20190617.

The first version of this series had 57 patches. The first part with 28 patches
were already merged. Right now, there are still ~76  patches pending applying
(including this series), and that's because I opted to do ~1 patch per converted
 directory.

That sounds too much to be send on a single round. So, I'm opting to split
it on 3 parts for the conversion, plus a final patch adding orphaned books
to existing ones.

Those patches should probably be good to be merged either by subsystem
maintainers or via the docs tree.

I opted to mark new files not included yet to the main index.rst (directly or
indirectly) with the :orphan: tag, in order to avoid adding warnings to the
build system. This should be removed after we find a "home" for all
the converted files within the new document tree arrangement, after I
submit the third part.

docs: filesystems: convert configfs.txt to ReST

- Add a SPDX header;
- Adjust document and section titles;
- Use copyright symbol;
- Some whitespace fixes and new line breaks;
- Mark literal blocks as such;
- Add it to filesystems/index.rst.

Also, as this file is alone on its own dir, and it doesn't
seem too likely that other documents will follow it, let's
move it to the filesystems/ root documentation dir.

scripts: sphinx-pre-install: change the output order

When the script detects the need for an upgrade, it will
print either a warning or a note.

Let's change a little bit the order where messages will be
displayed, in order to make easier for the user to identify
the more important messages.

It should now be like this:

Detected OS: Fedora release 31 (Thirty One).
Sphinx version: 1.7.9

Note: It is recommended at least Sphinx version 2.4.4 if you need PDF support.
To upgrade Sphinx, use:

/usr/bin/python3 -m venv sphinx_2.4.4
. sphinx_2.4.4/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt

If you want to exit the virtualenv, you can use:
deactivate

All optional dependencies are met.

scripts: sphinx-pre-install: fix a bug when using with venv

When python3 creates a venv, it adds python into it!

This causes any upgrade recommendation to look like this:

/devel/v4l/docs/sphinx_1.7.9/bin/python3 -m venv sphinx_2.4.4
. sphinx_2.4.4/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt

With is wrong (and it may not work). So, when recomending
an upgrade, exclude the venv dir from the search path, and
get the system's python.

scripts: sphinx-pre-install: change recommendation text if venv exists

If one is running a Sphinx version older than what's recommended,
but there's already a newer working virtual env, change the
text, as it is just a matter of switching to the new venv, instead
of creating a new one from scratch.

scripts: sphinx-pre-install: change the warning for version < 2.4.4

As requested by Jon, change the version check, in order to not
emit a warning if version is >= 1.7.9, but below 2.4.4.

After this patch, if someone used an older version, it will
say:

./scripts/sphinx-pre-install
Sphinx version 1.7.9
Note: It is recommended at least Sphinx version 2.4.4 if you need PDF support.
Detected OS: Fedora release 31 (Thirty One).

To upgrade Sphinx, use:

/devel/v4l/docs/sphinx_1.7.9/bin/python3 -m venv sphinx_2.4.4
. sphinx_2.4.4/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt

Merge branch 'mauro' into docs-next

Mauro sez:

Patches 1 to 5 contain changes to the documentation toolset:

- The first 3 patches help to reduce a lot the number of reported
  kernel-doc issues, by making the tool more smart.

- Patches 4 and 5 are meant to partially address the PDF
  build, with now requires Sphinx version 2.4 or upper.

The remaining patches fix broken references detected by
this tool:

        ./scripts/documentation-file-ref-check

and address other random errors due to tags being mis-interpreted
or mis-used.

They are independent each other, but some may depend on
the kernel-doc improvements.

lib: bitmap.c: get rid of some doc warnings

There are two ascii art drawings there. Use a block markup tag there
in order to get rid of those warnings:

./lib/bitmap.c:189: WARNING: Unexpected indentation.
./lib/bitmap.c:190: WARNING: Block quote ends without a blank line; unexpected unindent.
./lib/bitmap.c:190: WARNING: Unexpected indentation.
./lib/bitmap.c:191: WARNING: Line block ends without a blank line.

It should be noticed that there's actually a syntax violation
right now, as something like:

/**
 ...
 @src:

will be handled as a definition for @src parameter, and not as
part of a diagram. So, we need to add something before it, in
order for this to be processed the way it should.
