A routine check for misspelled Kconfig symbols showed on instance
from last year, the correct symbol name is CONFIG_ANDROID_BINDERFS,
not CONFIG_CONFIG_ANDROID_BINDERFS, so the extra prefix must
be removed in the Kconfig file to allow enabling the sample.
As the actual sample fails to build as a kernel module, change the
Makefile enough to get to build as a hostprog instead.

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.

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 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

say:

watchdog: clarify that stop() is optional
The commit d0684c8a9354 ("watchdog: Make stop function optional")
made stop function not mandatory, but the comments
and the doc weren't reflected. Fix it to clarify.
Changes to make the text more formal and organized. The reasons are now cited and described at the same time.
Minor grammatical problems have also been fixed.
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.
firewire: firewire-cdev.hL get rid of a docs warning
This warning:
./include/uapi/linux/firewire-cdev.h:312: WARNING: Inline literal start-string without end-string.
is because %FOO doesn't work if there's a parenthesis at the
string (as a parenthesis may indicate a function). So, mark
the literal block using the alternate ``FOO`` syntax.
docs: Makefile: place final pdf docs on a separate dir
The Sphinx build system for PDF is too complex and generate
lots of ancillary files, including one PDF file for each
image.
So, at the end, the main latex dir has 156 pdf files, instead
of the 71 ones that would match each generated book. That's
confusing and it makes harder to identify when something didn't
work.
So, instead, let's move the final PDF output(s) to a separate
dir. This way, the latex/ dir will have the temporary and the
final *.tex files, while the final pdf files that built ok
will be under the pdf/ directory.
When generating the PDF output, the Documentation/i2c dir
will generate an i2c.pdf. The same happens with i2c.svg:
it will also produce a file with the same name, at the same dir.
This causes errors when building the PDF output. So, rename the
image to i2c_bus.svg.
docs: mm: userfaultfd.rst: use a cross-reference for a section
Instead of using "foo", let's use `foo`_, with is a ReST way of
saying that foo is a section of the document. With that, after
building the docs, an hyperlink is generated.
docs: mm: userfaultfd.rst: use ``foo`` for literals
Several parts of this document define literals: ioctl names,
function calls, directory patches, etc. Mark those as literal
blocks, in order to improve its readability (both at text mode
and after parsed by Sphinx.
This fixes those two warnings:
Documentation/admin-guide/mm/userfaultfd.rst:139: WARNING: Inline emphasis start-string without end-string.
Documentation/admin-guide/mm/userfaultfd.rst:139: WARNING: Inline emphasis start-string without end-string.
Sphinx produce some warnings due to a bad table format:
Documentation/admin-guide/ras.rst:358: WARNING: Definition list ends without a blank line; unexpected unindent.
Documentation/admin-guide/ras.rst:358: WARNING: Definition list ends without a blank line; unexpected unindent.
Documentation/admin-guide/ras.rst:363: WARNING: Definition list ends without a blank line; unexpected unindent.
Documentation/admin-guide/ras.rst:363: WARNING: Definition list ends without a blank line; unexpected unindent.
Rearrange the things there in order to supress the warnings
while being precise at the Sphinx output about how ranks are
mapped into csrows.
Changeset f5a98bfe7b37 ("dt-bindings: display: Convert Allwinner display pipeline to schemas")
split Documentation/devicetree/bindings/display/sunxi/sun4i-drm.txt
into several files. Yet, it kept the old place at MAINTAINERS.
The building system can auto-generate a list of documents since
commit: 9d42afbe6bd4 ("docs: pdf: add all Documentation/*/index.rst to PDF output").
The added logic there allows keeping the existing list, but
there's not real reason to keep it. Now, the media document
has gone (it was split into tree).
So, it sounds about time to get rid of the manual entries,
and let the script to generate it automatically instead.
There are some docs that have nested tables. While this was
always part of the spec, only Sphinx version 2.4.x can
translate it to LaTeX.
In other words, if someone is using a Sphinx version < 2.4,
the LaTeX and PDF output won't work for some of the docs.
So, it seems that it is time to raise the bar again
for the recommented version.
The Sphinx check script is already smart enough to keep
working, with older versions, warning the users that
an upgrade is recommended (and explaining how):
Sphinx version 1.7.9
Warning: It is recommended at least Sphinx version 2.4.4.
Detected OS: Fedora release 31 (Thirty One).
scripts: kernel-doc: accept blank lines on parameter description
Sphinx is very pedantic with respect to blank lines. Sometimes,
in order to make it to properly handle something, we need to
add a blank line. However, currently, any blank line inside a
kernel-doc comment like:
/*
* @foo: bar
*
* foobar
*
* some description
will be considered as if "foobar" was part of the description.
This patch changes kernel-doc behavior. After it, foobar will
be considered as part of the parameter text. The description
will only be considered as such if it starts with:
The pattern @foo->bar() is valid, as it can be used by a
function pointer inside a struct passed as a parameter.
Right now, it causes a warning:
./drivers/firewire/core-transaction.c:606: WARNING: Inline strong start-string without end-string.
In this specific case, the kernel-doc markup is:
/**
* fw_core_remove_address_handler() - unregister an address handler
* @handler: callback
*
* To be called in process context.
*
* When fw_core_remove_address_handler() returns, @handler->callback() is
* guaranteed to not run on any CPU anymore.
*/
With seems valid on my eyes. So, instead of trying to hack
the kernel-doc markup, let's teach it about how to handle
such things. This should likely remove lots of other similar
warnings as well.
scripts: sphinx-pre-install: add support for python -m venv
Since python 3.3, the recommended way to setup a virtual env is
via "python -m venv".
Set this as a default, if python version is compatible with
such feature.
While here, add more comments to it, as the script is
getting more complex. So, better to add more things, to avoid
accidentally breaking it while improving it.
scripts: sphinx-pre-install: add support for OpenMandriva
It seems that Mageia and OpenMandriva will reunite on a single
distribution. In any case, both came from Mandriva. So, it is
close enough to use the same logic.
scripts: sphinx-pre-install: address some issues with Gentoo
There are some small misdetections with Gentoo. While they
don't cause too much trouble, it keeps recomending to
install things that are already there.
The Arch-linux detection is hit by catting /etc/issue, whose
contents is (nowadays):
Arch Linux \r (\l)
It sounds a little ackward to print such string, so,
instead, let's use the /etc/os-release file, with exists
on lots of distributions and should provide a more reliable
result.
We'll keep the old tests before it, in order to avoid possible
regressions with the other distros, although the new way should
probably work on all the currently supported distributions.
