Merge tag 'doc-4.8-fixes' of git://git.lwn.net/linux
Pull documentation fixes from Jonathan Corbet:
"Three fixes for the docs build, including removing an annoying warning
on 'make help' if sphinx isn't present"
* tag 'doc-4.8-fixes' of git://git.lwn.net/linux:
DocBook: use DOCBOOKS="" to ignore DocBooks instead of IGNORE_DOCBOOKS=1
Documenation: update cgroup's document path
Documentation/sphinx: do not warn about missing tools in 'make help'
Simply move the dochelp rule outside of the HAVE_SPHINX check,
overriding the .DEFAULT rule for HAVE_SPHINX=0.

Now that all media documentation was converted to Sphinx, we
should get rid of the old DocBook one, as we don't want people
to submit patches against the old stuff.

* 'docs-next' of git://git.lwn.net/linux:
doc-rst: add an option to ignore DocBooks when generating docs
workqueue: Fix a typo in workqueue.txt
Doc: ocfs: Fix typo in filesystems/ocfs2-online-filecheck.txt
Documentation/sphinx: skip build if user requested specific DOCBOOKS
Documentation: add cleanmediadocs to the documentation targets
The name of the subsystem is "media", and not "linux_tv". Also,
as we plan to add other stuff there in the future, let's
rename also the media uAPI book to media_uapi, to make it
clearer.
No functional changes.

This file is auto-generated with DocBook, from the uapi header.
Do the same with Sphinx.

If the user requested specific DocBooks to be built using 'make
DOCBOOKS=foo.xml htmldocs', assume no Sphinx build is desired. This
check is transitional, and can be removed once we drop the DocBook
build.

This was broken when updating the documentation targets for the Sphinx
build, and moving from %docs target pattern to explicitly listed
targets.

While there's slight overlap with the DocBook help now, this can stay
intact when the DocBook help goes away.

Read the version and release from the top level Makefile (for use when
Sphinx is invoked directly, by e.g. Read the Docs), but override them
via Sphinx command line arguments in a normal documentation build.

Tell Sphinx where to find the extension, and pass on the kernel src tree
and kernel-doc paths to the extension.
With this, any .rst files under Documentation may contain the kernel-doc
rst directive to include kernel-doc documentation from any source file.
While building, it may be handy to pass kernel-doc extension
configuration on the command line. For example, 'make SPHINXOPTS="-D
kerneldoc_verbosity=0" htmldocs' silences all stderr output from
kernel-doc when the kernel-doc exit code is 0. (The stderr will be
logged unconditionally when the exit code is non-zero.)

Add basic configuration and makefile to build documentation from any
.rst files under Documentation using Sphinx. For starters, there's just
the placeholder index.rst.
At the top level Makefile, hook Sphinx documentation targets alongside
(but independent of) the DocBook toolchain, having both be run on the
various 'make *docs' targets.
All Sphinx processing is placed into Documentation/Makefile.sphinx. Both
that and the Documentation/DocBook/Makefile are now expected to handle
all the documentation targets, explicitly ignoring them if they're not
relevant for that particular toolchain. The changes to the existing
DocBook Makefile are kept minimal.
There is graceful handling of missing Sphinx and rst2pdf (which is
needed for pdf output) by checking for the tool and python module,
respectively, with informative messages to the user.
If the Read the Docs theme (sphinx_rtd_theme) is available, use it, but
otherwise gracefully fall back to the Sphinx default theme, with an
informative message to the user, and slightly less pretty HTML output.
Sphinx can now handle htmldocs, pdfdocs (if rst2pdf is available),
epubdocs and xmldocs targets. The output documents are written into per
output type subdirectories under Documentation/output.
Finally, you can pass options to sphinx-build using the SPHINXBUILD make
variable. For example, 'make SPHINXOPTS=-v htmldocs' for more verbose
output from Sphinx.
This is based on the original work by Jonathan Corbet, but he probably
wouldn't recognize this as his own anymore.
