4f1bb0386d docs: create a top-level arch/ directory
As the first step in bringing some order to our architecture-specific
documentation, create a top-level arch/ directory and move arch.rst as its
index.rst file.

There is no change in the rendered docs at this point.

efe920466f docs: describe how to quickly build a trimmed kernel
Add a text explaining how to quickly build a kernel, as that's something
users will often have to do when they want to report an issue or test
proposed fixes. This is a huge and frightening task for quite a few
users these days, as many rely on pre-compiled kernels and have never
built their own. They find help on quite a few websites explaining the
process in various ways, but those howtos often omit important details
or make things too hard for the 'quickly build just for testing' case
that 'localmodconfig' is really useful for. Hence give users something
at hand to guide them, as that makes it easier for them to help with
testing, debugging, and fixing the kernel.

To keep the complexity at bay, the document explicitly focuses on how to
compile the kernel on commodity distributions running on commodity
hardware. People that deal with less common distributions or hardware
will often know their way around already anyway.

The text describes a few oddities of Arch and Debian that were found by
the author and a few volunteers that tested the described procedure.
There are likely more such quirks that need to be covered as well as a
few things the author will have missed -- but one has to start
somewhere.

The document heavily uses anchors and links to them, which makes things
slightly harder to read in the source form. But the intended target
audience is way more likely to read rendered versions of this text on
pages like docs.kernel.org anyway -- and there those anchors and links
allow easy jumps to the reference section and back, which makes the
document a lot easier to work with for the intended target audience.

Aspects relevant for bisection were left out on purpose, as that is a
related, but in the end different use case. The rough plan is to have a
second document with a similar style to cover bisection. The idea is to
reuse a few bits from this document and link quite often to entries in
the reference section with the help of the anchors in this text.

c500488f23 Documentation: kernel-parameters: sort NFS parameters
Sort the NFS kernel command line parameters. This is done in 4 groups
so as to not have them intermingled: 'nfs' module parameters, 'nfs4'
module parameters, 'nfsd' module parameters, and nfs "global" (__setup,
no module) parameters.

There were 5 parameters which were listed with a space between the
parameter name and the following '=' sign. The space has been
removed since module parameters expect 'parameter=' with no intervening
space.

10a29eb658 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.
