Jonathan Neuschäfer 2c1d7ffdf4 docs: admin-guide: Sort the "unordered guides" to avoid merge conflicts
Since the "unordered guides" linked in admin-guide/index.rst are not
supposed to be in any particular order, let's sort them alphabetically
to avoid the risk of merge conflicts by spreading newly added lines more
evenly.

Kees Cook aa20485528 doc-rst: Programmatically render MAINTAINERS into ReST
In order to have the MAINTAINERS file visible in the rendered ReST
output, this makes some small changes to the existing MAINTAINERS file
to allow for better machine processing, and adds a new Sphinx directive
"maintainers-include" to perform the rendering.

Features include:
- Per-subsystem reference links: subsystem maintainer entries can be
  trivially linked to both internally and external. For example:
  https://www.kernel.org/doc/html/latest/process/maintainers.html#secure-computing

- Internally referenced .rst files are linked so they can be followed
  when browsing the resulting rendering. This allows, for example, the
  future addition of maintainer profiles to be automatically linked.

- Field name expansion: instead of the short fields (e.g. "M", "F",
  "K"), use the indicated inline "full names" for the fields (which are
  marked with "*"s in MAINTAINERS) so that a rendered subsystem entry
  is more human readable. Email lists are additionally comma-separated.
  For example:

Kees Cook 1b1438b535 doc-rst: Reduce CSS padding around Field
Right now any ":Field Name: Field Contents" lines end up with significant
padding due to CSS from the "table" CSS which rightly needs padding to
make tables readable. However, field lists don't need this as they tend
to be stacked together. The future heavy use of fields in the parsed
MAINTAINERS file needs this cleaned up, and existing users look better
too. Note the needless white space (and misalignment of name/contents)
between "Date" and "Author":

https://www.kernel.org/doc/html/latest/accounting/psi.html

This patch fixes this by lowering the padding with a more specific CSS.

Jonathan Corbet 81929718b8 Merge branch 'dump-struct' into docs-next
André Almeida writes:

The current way that scripts/kernel-doc dump structs do not work for
nested structs with attributes (e.g. __packed) and without type alias
(e.g } alias1;). This is due to the way nested structs members are parsed.

Inside dump_struct(), the regex removes attributes and it surrounds
whitespaces. After that, it will do a foreach(id) loop for each alias.
However, we will have an empty string, and then the split function will
return nothing and the foreach will not have any iteration. The code will
then jump the loop and the substitution will fail since $newmember
is uninitialized.

This bug does not happen when the nested struct has no alias and no
attribute, since at process_proto_type() a whitespace is inserted in
order to ensure that the split will not fail. However, with any
attribute, this whitespace will be removed.

This patch solves this by replacing attributes with one whitespace, to
ensure that will have at least one whitespace.

Besides solving this bug at patch 1, I also add support for the
____cacheline_aligned_in_smp atribute at patch 2.

For testing and reproducing, create a file `code.h`:

/**
 * struct foobar - description
 * @number0: desc0
 * @number1: desc1
 * @number2: desc2
 */
struct foo {
	int number0;

	struct  {
		int number1;
	} __packed;

	struct {
		int number2;
	};

 };

I've tested with CRYPTO_MINALIGN_ATTR, __attribute__((__aligned__(8)))
and __aligned() as well. Now, run the `./script/kernel-doc code.h`,
and this is the output:

Use of uninitialized value $newmember in substitution (s///) at
./scripts/kernel-doc line 1152, <IN> line 18.

.. c:type:: struct foo

   description

**Definition**

::

  struct foo {
    int number0;
    struct {
      int number1;
    };
    struct {
      int number2;
    };
  };

**Members**

``number0``
  desc0

``{unnamed_struct}``
  anonymous

``number2``
  desc2

The output will not display the member number1 and will also display an
uninitialized warning. Running after the patch will get rid of the
warning and also display the description for number1:

[...]

**Members**

``number0``
  desc0

``{unnamed_struct}``
  anonymous

``number1``
  desc1

``{unnamed_struct}``
  anonymous

``number2``
  desc2

To test patch [2/2], just replace __packed for
____cacheline_aligned_in_smp and compare how, at the previous stage the
script believes ____cacheline... is an alias for the struct and after
the patch it is removed just as the others attributes.

Finally, I have compared the output of "make htmldocs" with and without
this patch. No new warning were found and one warning regarding
____cacheline_aligned_in_smp at include/linux/netdevice.h was removed.

André Almeida f861537d5f kernel-doc: add support for ____cacheline_aligned_in_smp attribute
Subroutine dump_struct uses type attributes to check if the struct
syntax is valid. Then, it removes all attributes before using it for
output. `____cacheline_aligned_in_smp` is an attribute that is
not included in both steps. Add it, since it is used by kernel structs.

André Almeida 2b5f78e5e9 kernel-doc: fix processing nested structs with attributes
The current regular expression for strip attributes of structs (and
for nested ones as well) also removes all whitespaces that may
surround the attribute. After that, the code will split structs and
iterate for each symbol separated by comma at the end of struct
definition (e.g. "} alias1, alias2;"). However, if the nested struct
does not have any alias and has an attribute, it will result in a
empty string at the closing bracket (e.g "};"). This will make the
split return nothing and $newmember will keep uninitialized. Fix
that, by ensuring that the attribute substitution will leave at least
one whitespace.

Kees Cook 29efbb24d9 docs: Use make invocation's -j argument for parallelism
While sphinx 1.7 and later supports "-jauto" for parallelism, this
effectively ignores the "-j" flag used in the "make" invocation, which
may cause confusion for build systems. Instead, extract the available
parallelism from "make"'s job server (since it is not exposed in any
special variables) and use that for the "sphinx-build" run. Now things
work correctly for builds where -j is specified at the top-level:

	make -j16 htmldocs

If -j is not specified, continue to fallback to "-jauto" if available.
