[PATCH v2 00/16] Add support to generate ABI documentation at admin-guide

[Mauro Carvalho Chehab <mchehab+samsung@kernel.org>]

Greg,

In time: forgot to add a 00/16 patch... someone come to my desk while I was
sending this... sorry for that.

That's the second version of the doc ABI updated logic.

Changes from version 1:

- I updated my e-mail on older patches;

- Two new ABI fix patches;

- Improved the parser to detect a few more issues I discovered on
  some ABI files.

- There's now a "validate" command at get_abi.pl. It simply runs
  the parser without any output, except for warnings;

- It now runs "get_abi.pl validate" during the build (if enabled).

Please notice that the last patch will conflict with another patch
merged via docs-next tree, with creates a Documentation/Kconfig and
adds a check at Documentation/Makefile for broken documentation
links. The conflict is trivial to solve, through: just add the contents
on both tress.

This series is based on your driver-core git tree.

-

On this series:

- The first two patches contain two extra ABI fixes;

- The next 10 patches contain the ABI parsing script. I don't
  mind if you prefer folding them on a single patch, but IMO,
  preserving the history may help tracking bugs, if any;

- The 13th patch adds the new script to the documentation build
  system, together with a new python Sphinx extension with calls it;

- The 14th patch fixes the python script when running with newer
  Sphinx versions (1.7 and upper);

- The 15th patch fixes an UTF-8 troubles;

- The final patch adds a Kconfig var that will check for ABI
  file problems, if COMPILE_TEST and WARN_ABI_ERRORS are
  enabled.
