      Merge branch 'mauro' into docs-next · 769f90f8

      Mauro says (as he's cleaning up my mess):

This small series address a regression caused by a new patch at
docs-next (and at linux-next).

Before this patch, when a cross-reference to a chapter within the
documentation is needed, we had to add a markup like:

	.. _foo:

	foo
	===

This behavor is now different after this patch:

	58ad30cf ("docs: fix reference to core-api/namespaces.rst")

As a Sphinx extension now creates automatically a reference
like the above, without requiring any extra markup.

That, however, comes with a price: it is not possible anymore to have
two sections with the same name within the entire Kernel docs!

This causes thousands of warnings, as we have sections named
"introduction" on lots of places.

This series solve this regression by doing two changes:

1) The references are now prefixed by the document name. So,
   a file named "bar" would have the "foo" reference as "bar:foo".

2) It will only use the first two levels. The first one is (usually) the
   name of the document, and the second one the chapter name.

This solves almost all problems we have. Still, there are a few places
where we have two chapters at the same document with the
same name. The first patch addresses this problem.

The second patch limits the escope of the autosectionlabel.

      docs: conf.py: avoid thousands of duplicate label warning on Sphinx · 4658b0eb
      Mauro Carvalho Chehab authored 
      The autosectionlabel extension is nice, as it allows to refer to
a section by its name without requiring any extra tag to create
a reference name.

However, on its default, it has two serious problems:

1) the namespace is global. So, two files with different
   "introduction" section would create a label with the
   same name. This is easily solvable by forcing the extension
   to prepend the file name with:

	autosectionlabel_prefix_document = True

2) It doesn't work hierarchically. So, if there are two level 1
   sessions (let's say, one labeled "open" and another one "ioctl")
   and both have a level 2 "synopsis" label, both section 2 will
   have the same identical name.

   Currently, there's no way to tell Sphinx to create an
   hierarchical reference like:

		open / synopsis
		ioctl / synopsis

  This causes around 800 warnings. So, the fix should be to
  not let autosectionlabel to produce references for anything
  that it is not at a chapter level within any doc, with:

	autosectionlabel_maxdepth = 2

      docs: prevent warnings due to autosectionlabel · c44166fe
      Mauro Carvalho Chehab authored 
      Changeset 58ad30cf ("docs: fix reference to core-api/namespaces.rst")
enabled a new feature at Sphinx: it will now generate index for each
document title, plus to each chapter inside it.

There's a drawback, though: one document cannot have two sections
with the same name anymore.

A followup patch will change the logic of autosectionlabel to
avoid most creating references for every single section title,
but still we need to be able to reference the chapters inside
a document.

There are a few places where there are two chapters with the
same name. This patch renames one of the chapters, in order to
avoid symbol conflict within the same document.

PS.: as I don't speach Chinese, I had some help from a friend
(Wen Liu) at the Chinese translation for "publishing patches"
for this document:
