As people browsing this document may not notice that the source
file title is "stable_api_nonsense", I opted to use bold to
the rationale for this document. I also found it better to
add a note when it says that the nonsense applies only to the
kABI/kAPI, and not to uAPI.

Sphinx doesn't accept underline markups by purpose.
While there are ways to support underline via CSS, this won't

On Sphinx/ReST notation, ``foo`` means that foo will be will be
marked as inline literal, effectively making it to be presented
as a monospaced font.

As we want this document to be parsed by Sphinx, instead of using
"foo", use ``foo`` for the names that are literal, because it is an
usual typographic convention to use monospaced fonts for functions
and language commands on documents, and we're following such
convention on the other ReST books.

As discussed at linux-doc ML, the best is to keep all documents
backward compatible with Sphinx version 1.2, as it is the latest
version found on some distros like Debian.

All books currently support it.

Please notice that, while it mentions the eventual need of
XeLaTex and texlive to build pdf files, this is not a minimal
requirement, as one could just be interested on building html
documents. Also, identifying the minimal requirements for
texlive packages is not trivial, as each distribution seems to
use different criteria on grouping LaTex functionalities.

While here, update the current kernel version to 4.x.

This short series convers device-drivers.tmpl into the RST format, splits
it up, and sets up the result under Documentation/driver-api/.  For added
fun, I've taken one top-level file (hsi.txt) and folded it into the
document as a way of showing the direction I'm thinking I would like things
to go.  There is plenty more of this sort of work that could be done, to
say the least - this is just a beginning!

The formatted results can be seen at:

    http://static.lwn.net/kerneldoc/driver-api/index.html

As part of the long-term task to turn Documentation/ into less of a horror
movie, I'd like to collect documentation of the driver-specific API here.
Arguably gpu/ and the media API stuff should eventually move here, though
we can discuss the color of that particular shed some other day.
Meanwhile, I'd appreciate comments on the general idea.

No need to be be, just be should be sufficient.

- The guide currently says to pad the structure to a multiple of
  64-bits. This is not necessary in cases where the structure contains
  no 64-bit types. Clarify this concept to avoid unnecessary padding.
- When using __u64 to hold user pointers, blindly trying to do a cast to
  a void __user * may generate a warning on 32-bit systems about a cast
  from an integer to a pointer of different size. There is a macro to
  deal with this which hides an ugly double cast. Add a reference to
  this macro.

The setup() function of a Sphinx-extension can return a dictionary. This
is treated by Sphinx as metadata of the extension [1].

With metadata "parallel_read_safe = True" a extension is marked as
save for "parallel reading of source". This is needed if you want
build in parallel with N processes. E.g.:

  make SPHINXOPTS=-j4 htmldocs

will no longer log warnings like:

  WARNING: the foobar extension does not declare if it is safe for
  parallel reading, assuming it isn't - please ask the extension author
  to check and make it explicit.

Add metadata to extensions:

* kernel-doc
* flat-table
* kernel-include

When using a typedef function like this one:
	typedef bool v4l2_check_dv_timings_fnc (const struct v4l2_dv_timings * t, void * handle);

The Sphinx C domain expects it to create a c:type: reference,
as that's the way it creates the type references when parsing
a c:function:: declaration.

So, a declaration like:

	.. c:function:: bool v4l2_valid_dv_timings (const struct v4l2_dv_timings * t, const struct v4l2_dv_timings_cap * cap, v4l2_check_dv_timings_fnc fnc, void * fnc_handle)

Will create a cross reference for :c:type:`v4l2_check_dv_timings_fnc`.

So, when outputting such typedefs in RST format, we need to handle
this special case, as otherwise it will produce those warnings:

	./include/media/v4l2-dv-timings.h:43: WARNING: c:type reference target not found: v4l2_check_dv_timings_fnc
	./include/media/v4l2-dv-timings.h:60: WARNING: c:type reference target not found: v4l2_check_dv_timings_fnc
	./include/media/v4l2-dv-timings.h:81: WARNING: c:type reference target not found: v4l2_check_dv_timings_fnc

So, change the kernel-doc script to produce a RST output for the
above typedef as:
	.. c:type:: v4l2_check_dv_timings_fnc

	   **Typedef**: timings check callback

	**Syntax**

	  ``bool v4l2_check_dv_timings_fnc (const struct v4l2_dv_timings * t, void * handle);``
