There are 4 IRQ documentation files under Documentation/*.txt.
Move them into a new directory (core-api/irq) and add a new
index file for it.
While here, use a title markup for the Debugging section of the
irq-domain.rst file.

There is an special chapter inside the core-api book about
some debug infrastructure like tracepoints and debug objects.
It sounded to me that this is the best place to add a chapter
explaining how to use a FireWire controller to do remote
kernel debugging, as explained on this document.

Make some miscellaneous fixes to the first paragraph of "ECC memory":
- Change the incorrect "74 bits" to "72 bits".
- Change "mentioned on" to "mentioned in".
- Remove the extra "extra".
- Rephrase some sentences as suggested by Matthew Wilcox.

During recent patch discussion [1] it became apparent that the "other_node"
definition in the numastat documentation has always been different from actual
implementation. It was also noted that the stats can be innacurate on systems
with memoryless nodes.
This patch corrects the other_node definition (with minor tweaks to two more
definitions), adds a note about memoryless nodes and also two introductory
paragraphs to the numastat documentation.

A routine check for misspelled Kconfig symbols showed on instance
from last year, the correct symbol name is CONFIG_ANDROID_BINDERFS,
not CONFIG_CONFIG_ANDROID_BINDERFS, so the extra prefix must
be removed in the Kconfig file to allow enabling the sample.
As the actual sample fails to build as a kernel module, change the
Makefile enough to get to build as a hostprog instead.

Mauro says:
This is the second part of a series I wrote sometime ago where I manually
convert lots of files to be properly parsed by Sphinx as ReST files.
As it touches on lot of stuff, this series is based on today's linux-next,
at tag next-20190617.
The first version of this series had 57 patches. The first part with 28 patches
were already merged. Right now, there are still ~76 patches pending applying
(including this series), and that's because I opted to do ~1 patch per converted
directory.
That sounds too much to be send on a single round. So, I'm opting to split
it on 3 parts for the conversion, plus a final patch adding orphaned books
to existing ones.
Those patches should probably be good to be merged either by subsystem
maintainers or via the docs tree.
I opted to mark new files not included yet to the main index.rst (directly or
indirectly) with the :orphan: tag, in order to avoid adding warnings to the
build system. This should be removed after we find a "home" for all
the converted files within the new document tree arrangement, after I
submit the third part.
- Add a SPDX header;
- Adjust document and section titles;
- Use copyright symbol;
- Some whitespace fixes and new line breaks;
- Mark literal blocks as such;
- Add it to filesystems/index.rst.
Also, as this file is alone on its own dir, and it doesn't
seem too likely that other documents will follow it, let's
move it to the filesystems/ root documentation dir.

This document has its own style. It seems to be print output
for the old matrixial printers where backspace were used to
do double prints.
For the conversion, I used several regex expressions to get
rid of some weird stuff. The patch also does almost all possible
conversions in order to get a nice output document, while keeping
it readable/editable as is:
- Add a SPDX header;
- Add a document title;
- Adjust document title;
- Adjust section titles;
- Some whitespace fixes and new line breaks;
- Mark literal blocks as such;
- Adjust list markups;
- Mark some unumbered titles with bold font;
- Use footnoote markups;
- Add table markups;
- Use notes markups;
- Add it to filesystems/index.rst.
