Add guidance for AI assistants and developers using AI tools for kernel
contributions, per the consensus reached at the 2025 Maintainers Summit.
Create Documentation/process/coding-assistants.rst with detailed guidance
on licensing, Signed-off-by requirements, and attribution format. The
README points AI tools to this documentation.
This will allow coding assistants to easily parse these instructions and
comply with guidelines set by the community.

The memory-barriers.txt Korean translation is quite outdated. The last
update on the translation was made on 2022-10-10, by commit ee5a86f451
("docs/memory-barriers.txt/kokr: Fix confusing name of 'data dependency
barrier'"). After the date, the original memory-barriers.txt got seven
more changes so far. The most recent one was made on 2025-11-05. But
none of those are applied to the translation.
Maybe I can work again on keeping it updated. But, given the
advancement of translation tools, I think it might not be worth keeping
it at all. Remove the outdated translation.
If it turns out to be worthy to keep the translation and someone willing
to keep it updated steps up, this could be reverted.
This change was inspired from the last kernel summit discussion [1].

For review of patches that revisioned multiple times, patch changelogs
are very useful. Adding actual links to the previous versions can
further help the review. Using such links, reviewers can double check
the changelog by themselves, and find previous discussions. Nowadays
having such links (e.g., lore.kernel.org archive links) is easy and
reliable. Suggest adding such links if available.

The documentation states that:
make W=n
can be used to verify the documentation format. This is true for .c
files but not for headers [1].
Modify the documentation to specify that headers files are not covered
by make W=n and that these need to be checked separately with
scripts/kernel-doc.

While reading the git-format-patch manpages [1], I discovered the existence
of the "Toggle Line Wrap" extension for Thunderbird which I found rather
convenient.
Looking at the history, the ancestor of this extension was added to the
documentation in commit e0e34e977a ("Documentation/email-clients.txt:
update Thunderbird docs with wordwrap plugin") but then removed in commit
f9a0974d3f ("Documentation: update thunderbird email client settings").
Extend the paragraph on Thunderbird's mailnews.wraplength register to
mention the existence of the "Toggle Line Wrap" extension. The goal is not
to create a war on what is the best option so make it clear that this is
just an alternative.

The recent move of this script from scripts/ to tools/docs/
did not account for the 'cd' directory usage.
Update "cd .." to "cd ../.." to make the script self-correcting.
This also eliminates a shell warning:
./tools/docs/find-unused-docs.sh: line 33: cd: Documentation/: No such file or directory

Commit 4843a45ef9fe8 ("entry: Rename "kvm" entry code assets to "virt"
to genericize APIs") renames the config KVM_XFER_TO_GUEST_WORK to
VIRT_XFER_TO_GUEST_WORK.
Adjust the documentation to the current situation, and specifically
refer to the new name of the config.

Some thoughts on hardware that is used for real-time workload. Certainly
not complete but should cover some of the import topics such as:
- Main memory, caches and the possiblie control given by the hardware.
- What could happen by putting critical hardware behind USB or VirtIO.
- Allowing real-time tasks to consume the CPU entirely without giving
the system some time to breath.
- Networking with what the kernel provides.

As the trend of AI-generated reports is growing, the trend of unreadable
reports in gimmicky formats is following, and we cannot request that
developers rely on online viewers to be able to read a security report
full for formatting tags. Let's just insist on the plain text requirement
a bit more.
