Mauro Carvalho Chehab 02bba8ca90 scripts: sphinx-pre-install: place a warning for Sphinx >= 3.0
Newer versions of Sphinx have a known bug:
	https://github.com/sphinx-doc/sphinx/pull/8313

Those currently produces 11 false-positive warnings On Sphinx
version 3.1+.

While Sphinx fix is not applied, let's warn adventurers that would
be using Sphinx installed via distro packages.

As it is not a consensus about installing sphinx using venv, and
modern distributions are now shipping with Sphinx versions above
the minimal requirements to build the docs, provide both venv
and package install commands by default.

Mauro Carvalho Chehab e50899122f scripts: sphinx-pre-install: rework the sphinx install logic
The sphinx-pre-install supports installing sphinx via a virtual
environment using pip/pypi or directly from the distribution's
package, when --no-virtualenv is used.

However, even when --no-virtualenv, the current logic is
still recomending to install a virtual env, due to a regression.

It turns that the logic there is complex, as it depends on
several different conditions.

Split the code which recommends Sphinx on two separate
functions, in order to clean up the code.

Jonathan Corbet 2f444efdaa docs: Don't push Sphinx upgrades quite so readily
The sphinx-pre-install script will put out a verbose message recommending
an upgrade for anybody running less than 2.4.4 - which was only released in
March.  So *everybody* will see that warning at this point.  Let's only
warn if the user is below our generally recommended version (1.7.9
currently).

It might be good to put out a warning if people are explicitly making PDF
files, but would need to be done in a different place and relatively few
people do that.

Mauro Carvalho Chehab ec43a27fff 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.
Needed package dependencies are met.

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

This causes any upgrade recommendation to look like this:

	. 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.

Tim Bird c428cd5228 scripts/sphinx-pre-install: add '-p python3' to virtualenv
With Ubuntu 16.04 (and presumably Debian distros of the same age),
the instructions for setting up a python virtual environment should
do so with the python 3 interpreter.  On these older distros, the
default python (and virtualenv command) might be python2 based.

Some of the packages that sphinx relies on are now only available
for python3.  If you don't specify the python3 interpreter for
the virtualenv, you get errors when doing the pip installs for
various packages

Fix this by adding '-p python3' to the virtualenv recommendation
line.

Linus Torvalds 2f4c533499 SPDX update for 5.2-rc3, round 1
Here is another set of reviewed patches that adds SPDX tags to different
 kernel files, based on a set of rules that are being used to parse the
 comments to try to determine that the license of the file is
 "GPL-2.0-or-later" or "GPL-2.0-only".  Only the "obvious" versions of
 these matches are included here, a number of "non-obvious" variants of
 text have been found but those have been postponed for later review and
 analysis.
 
 There is also a patch in here to add the proper SPDX header to a bunch
 of Kbuild files that we have missed in the past due to new files being
 added and forgetting that Kbuild uses two different file names for
 Makefiles.  This issue was reported by the Kbuild maintainer.
 
 These patches have been out for review on the linux-spdx@vger mailing
 list, and while they were created by automatic tools, they were
 hand-verified by a bunch of different people, all whom names are on the
 patches are reviewers.

Mauro Carvalho Chehab 9b88ad5464 scripts/sphinx-pre-install: always check if version is compatible with build
Call the script every time a make docs target is selected, on
a simplified check mode.

With this change, the script will set two vars:

$min_version - obtained from `needs_sphinx` var inside
	       conf.py (currently, '1.3')

$rec_version - obtained from sphinx/requirements.txt.

With those changes, a target like "make htmldocs" will do:

1) If no sphinx-build/sphinx-build3 is found, it will run
   the script on normal mode as before, checking for all
   system dependencies and providing install hints for the
   needed programs and will abort the build;

2) If no sphinx-build/sphinx-build3 is found, but there is
   a sphinx_${VER}/bin/activate file, and if
   ${VER} >= $min_version (string comparation), it will
   run in full mode, and will recommend to activate the
   virtualenv. If there are multiple virtualenvs, it
   will string sort the versions, recommending the
   highest version and will abort the build;

3) If Sphinx is detected but has a version lower than
   $min_version, it will run in full mode - with will
   recommend creating a virtual env using sphinx/requirements.txt,
   and will abort the build.

4) If Sphinx is detected and version is lower than
   $rec_version, it will run in full mode and will
   recommend creating a virtual env using sphinx/requirements.txt.

   In this case, it **won't** abort the build.

5) If Sphinx is detected and version is equal or righer than
   $rec_version it will return just after detecting the
   version ("quick mode"), not checking if are there any
   missing dependencies.

Just like before, if one wants to install Sphinx from the
distro, it has to call the script manually and use `--no-virtualenv`
argument to get the hints for his OS:

    You should run:

	sudo dnf install -y python3-sphinx python3-sphinx_rtd_theme

While here, add a small help for the three optional arguments
for the script.

RHEL8 was already launched. This test won't get it, and will

Sphinx version to ensure that it matches the minimal (1.3),

Mauro Carvalho Chehab 54d6d73f50 docs-rst: don't require adjustbox anymore
Only the media PDF book was requiring adjustbox, in order to
scale big tables. That worked pretty good with Sphinx versions
1.4 and 1.5, but Spinx 1.6 changed the way tables are produced,
by introducing some weird macros before tabulary.
That causes adjustbox to fail. So, it can't be used anymore,
and its usage was removed from the media book.

So, let's remove it from conf.py and sphinx-pre-install.

Mauro Carvalho Chehab 9b756a9d07 scripts/sphinx-pre-install: add minimum support for RHEL
RHEL 7.x and clone distros are shipped with Sphinx 1.1.x,
with is incompatible with Kernel ReST markups.

So, on those systems, the only alternative is to install
it via a Python virtual environment.

While seeking for "pip" on CentOS 7.3, I noticed that it
is not really needed, as python-virtualenv has its version
packaged there already. So, remove this from the list of
requirements for all distributions.

With regards to PDF, we need at least texlive-tabulary
extension, but that is not shipped there (at least on
CentOS). So, disable PDF packages as a whole.

Please notice, however, that texlive + amsmath is needed for
ReST to properly handle ReST ".. math::" tags. Yet, Sphinx
fall back to display the LaTeX math expressions as-is, if
such extension is not available.

So, let's just disable all texlive packages as a whole.

Add support for detecting and installing missing packages
on Mageia. I opted to use "urpmi" at the install instructions,
as this is present on Mageia since ever. Yet, if I were using
Mageia 6, I would likely be using "dnf", as it is, IMHO,
easier to use.
