docs: add backporting and conflict resolution document

This is a new document based on my 2022 blog post:

https://blogs.oracle.com/linux/post/backporting-patches-using-git

Although this is aimed at stable contributors and distro maintainers,
it does also contain useful tips and tricks for anybody who needs to
resolve merge conflicts.

By adding this to the kernel as documentation we can more easily point
to it e.g. from stable emails about failed backports, as well as allow
the community to modify it over time if necessary.

I've added this under process/ since it also has
process/applying-patches.rst. Another interesting document is
maintainer/rebasing-and-merging.rst which maybe should eventually refer
to this one, but I'm leaving that as a future cleanup.

Thanks to Harshit Mogalapalli for helping with the original blog post
as well as this updated document and Bagas Sanjaya for providing
thoughtful feedback.

Documentation/process: Add Linux Kernel Contribution Maturity Model

As a follow-up to a discussion at the 2021 Maintainer's Summit on the
topic of maintainer recruitment and retention, the TAB took on the
task of creating a document which to help companies and other
organizations to grow in their ability to engage with the Linux Kernel
development community, using the Maturity Model[2] framework.

The goal is to encourage, in a management-friendly way, companies to
allow their engineers to contribute with the upstream Linux Kernel
development community, so we can grow the "talent pipeline" for
contributors to become respected leaders, and eventually kernel
maintainers.

Create a new section for security issues in the index and group it with

I'm doing this at the start of the series to make all the subsequent

Existing references were updated using:

Notably, the page is not moved in the translations (due to my lack of

to point to the new location of the original document where these
references exist.

docs: process: remove outdated submitting-drivers.rst

Commit 31b24bee3357 ("docs: add a warning to submitting-drivers.rst")
in October 2016 already warns "This (...) should maybe just be deleted,
but I'm not quite ready to do that yet".

Maybe, six years ago, we were not ready but let us remove old content
for the better now and structure and maintain less content in the kernel
documentation with a better result.

Drop this already outdated document and adjust all textual references.

Here is an argument why deleting the content will not remove any useful
information to the existing kernel documentation, individually broken down
for each section.

Section "Allocating Device Numbers" refers to https://www.lanana.org/, and
then refers to Documentation/admin-guide/devices.rst.

However, the devices.rst clearly states:

"The version of this document at lanana.org is no longer maintained."

Everything needed for submitting drivers is already stated in devices.rst
and the reference to https://www.lanana.org/ is outdated, and should be
just deleted.

Section "Who To Submit Drivers To" is all about Linux 2.0 - 2.6, before
the new release version scheme; the mentioned developers are still around,
but actually not the first developers to contact anymore.

Section "What Criteria Determine Acceptance" has a few bullet points:

Licensing and Copyright is well-covered in process/kernel-license.rst.

Interfaces, Code, Portability, Clarity state some obvious things about
ensuring kernel code quality.

Control suggests to add a MAINTAINERS entry, which is already mentioned in
6.Followthrough.rst: "... added yourself to the MAINTAINERS file..."

PM support states a bit about implementing and testing power management of
a driver, it remains an open question where to place that in the process
documents. Driver developers interested in power management will find the
corresponding part on power management in the kernel documentation anyway.

In section "What Criteria Do Not Determine Acceptance", the points Vendor
and Author states something basic consequence of the kernel being an
open-source community software development. Probably no need to mention it
nowadays.

Section "Resources" lists resources that are also mentioned elsewhere more
central.

The texts among others describes the first rule of Linux kernel
development and what it means in practice. They also explain what a
regression actually is and how to report one properly.

Both texts additionally provide a brief introduction to the bot the
kernel's regression tracker uses to facilitate the work, but mention the
use is optional.

To sum things up, provide a few quotes from Linus in the document for
developers to show how serious we take regressions.

Documentation: riscv: add patch acceptance guidelines

Formalize, in kernel documentation, the patch acceptance policy for
arch/riscv. In summary, it states that as maintainers, we plan to
only accept patches for new modules or extensions that have been
frozen or ratified by the RISC-V Foundation.

We've been following these guidelines for the past few months. In the
meantime, we've received quite a bit of feedback that it would be
helpful to have these guidelines formally documented.

Based on a suggestion from Matthew Wilcox, we also add a link to this
file to Documentation/process/index.rst, to make this document easier
to find. The format of this document has also been changed to align
to the format outlined in the maintainer entry profiles, in accordance
with comments from Jon Corbet and Dan Williams.

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:

Documentation/process: Embargoed hardware security issues

To address the requirements of embargoed hardware issues, like Meltdown,
Spectre, L1TF etc. it is necessary to define and document a process for
handling embargoed hardware security issues.

Following the discussion at the maintainer summit 2018 in Edinburgh
(https://lwn.net/Articles/769417/) the volunteered people have worked
out a process and a Memorandum of Understanding. The latter addresses
the fact that the Linux kernel community cannot sign NDAs for various
reasons.

The initial contact point for hardware security issues is different from
the regular kernel security contact to provide a known and neutral
interface for hardware vendors and researchers. The initial primary
contact team is proposed to be staffed by Linux Foundation Fellows, who
are not associated to a vendor or a distribution and are well connected
in the industry as a whole.

The process is designed with the experience of the past incidents in
mind and tries to address the remaining gaps, so future (hopefully rare)
incidents can be handled more efficiently. It won't remove the fact,
that most of this has to be done behind closed doors, but it is set up
to avoid big bureaucratic hurdles for individual developers.

The process is solely for handling hardware security issues and cannot
be used for regular kernel (software only) security bugs.

This memo can help with hardware companies who, and I quote, "[my
manager] doesn't want to bet his job on the list keeping things secret."
This despite numerous leaks directly from that company over the years,
and none ever so far from the kernel security team. Cognitive
dissidence seems to be a requirement to be a good manager.

To accelerate the adoption of this process, we introduce the concept of
ambassadors in participating companies. The ambassadors are there to
guide people to comply with the process, but are not automatically
involved in the disclosure of a particular incident.

Code of Conduct Interpretation: Add document explaining how the Code of Conduct is to be interpreted

The Contributor Covenant Code of Conduct is a general document meant to
provide a set of rules for almost any open source community. Every
open-source community is unique and the Linux kernel is no exception.
Because of this, this document describes how we in the Linux kernel
community will interpret it. We also do not expect this interpretation
to be static over time, and will adjust it as needed.

This document was created with the input and feedback of the TAB as well
as many current kernel maintainers.

Code of Conduct: Let's revamp it.

The Code of Conflict is not achieving its implicit goal of fostering
civility and the spirit of 'be excellent to each other'. Explicit
guidelines have demonstrated success in other projects and other areas
of the kernel.

Here is a Code of Conduct statement for the wider kernel. It is based
on the Contributor Covenant as described at www.contributor-covenant.org

From this point forward, we should abide by these rules in order to help
make the kernel community a welcoming environment to participate in.

docs: tidy up TOCs and refs to license-rules.rst

The documentation and TOCs are organized in a manner of a tree. Adding a TOC to
the root, which refers to a file which is located in a subfolder forms a
grid. Those TOCs are a bit confusing and thats why we get additional error
messages while building partial documentation::

$ make SPHINXDIRS=process htmldocs
...
checking consistency... Documentation/process/license-rules.rst: \
WARNING: document isn't included in any toctree

To fix it, the *root-license-TOC* is replaced by a reference and the
'license-roles.txt' is added to the Documentation/process/index.rst TOC.

BTW: there was an old licences remark in Documentation/process/howto.rst which
is also updated, mentioning SPDX and pointing to the license-rules.rst

Documentation/process: kernel maintainer PGP guide

This guide is an adapted version of the more general "Protecting Code
Integrity" guide written and maintained by The Linux Foundation IT for
use with open-source projects. It provides the oft-lacking guidance on
the following topics:

- how to properly protect one's PGP keys to minimize the risks of them
being stolen and used maliciously to impersonate a kernel developer
- how to configure Git to properly use GnuPG
- when and how to use PGP with Git
- how to verify fellow Linux Kernel developer identities

I believe this document should live with the rest of the documentation
describing proper processes one should follow when participating in
kernel development. Placing it in a wiki on some place like kernel.org
would be insufficient for a number of reasons -- primarily, because only
a relatively small subset of maintainers have accounts on kernel.org,
but also because even those who do rarely remember that such wiki
exists. Keeping it with the rest of in-kernel docs should hopefully give
it more visibility, but also help keep it up-to-date as tools and
processes evolve.
