docs: stable-kernel-rules: improve structure by changing headlines

docs: stable-kernel-rules: make rule section more straight forward
Tweak some of the rule text to make things more straight forward, with the goal to stick closely to the intend of the old text: * put the "it or equivalent fix must be upstream" rule at the top, as it's one of the most important ones that at the same time often seems to be missed by developers. * "It must fix only one thing" was dropped, as that is almost always a thing that needs to be handled earlier when the change is mainlined. Furthermore, this is already indirectly covered by the "Separate your changes" section in Documentation/process/submitting-patches.rst which the rules already point to. * six other rules are in the end one rule with clarifications; structure the text accordingly to make it a lot easier to follow and understand the intend. * drop the 'In short, something critical' from one of those notes: it contradicts the "real bug that bothers people" aspect somewhat and does not really add anything CC: Greg KH <gregkh@linuxfoundation.org> CC: Sasha Levin <sashal@kernel.org> CC: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Thorsten Leemhuis <linux@leemhuis.info> Link: https://lore.kernel.org/r/f83e812879caa978a51a1a7cae7c359f29fc093c.1689056247.git.linux@leemhuis.info Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

Documentation: embargoed-hardware-issues.rst: add AMD to the list
Add AMD back to the embargoed-hardware-issues.rst list. There was confusion about a recent issue that ended up being due to third-party's misrepresentation, not AMD, so add AMD back to the list to get notified properly as they understand the proper procedures to follow.

Documentation: security-bugs.rst: update preferences when dealing with the linux-distros group
Because the linux-distros group forces reporters to release information about reported bugs, and they impose arbitrary deadlines in having those bugs fixed despite not actually being kernel developers, the kernel security team recommends not interacting with them at all as this just causes confusion and the early-release of reported security problems.

ARM64:
* Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of hugepage splitting in the stage-2
fault path.
* Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
services that live in the Secure world. pKVM intervenes on FF-A calls
to guarantee the host doesn't misuse memory donated to the hyp or a
pKVM guest.
* Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
* Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set configuration
from userspace, but the intent is to relax this limitation and allow
userspace to select a feature set consistent with the CPU.
* Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
* Use a separate set of pointer authentication keys for the hypervisor
when running in protected mode, as the host is untrusted at runtime.
* Ensure timer IRQs are consistently released in the init failure
paths.
* Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
(FEAT_EVT), as it is a register commonly read from userspace.
* Erratum workaround for the upcoming AmpereOne part, which has broken
hardware A/D state management.
RISC-V:
* Redirect AMO load/store misaligned traps to KVM guest
* Trap-n-emulate AIA in-kernel irqchip for KVM guest
* Svnapot support for KVM Guest
s390:
* New uvdevice secret API
* CMM selftest and fixes
* fix racy access to target CPU for diag 9c
x86:
* Fix missing/incorrect #GP checks on ENCLS
* Use standard mmu_notifier hooks for handling APIC access page
* Drop now unnecessary TR/TSS load after VM-Exit on AMD
* Print more descriptive information about the status of SEV and SEV-ES during
module load
* Add a test for splitting and reconstituting hugepages during and after
dirty logging
* Add support for CPU pinning in demand paging test
* Add support for AMD PerfMonV2, with a variety of cleanups and minor fixes
included along the way
* Add a "nx_huge_pages=never" option to effectively avoid creating NX hugepage
recovery threads (because nx_huge_pages=off can be toggled at runtime)
* Move handling of PAT out of MTRR code and dedup SVM+VMX code
* Fix output of PIC poll command emulation when there's an interrupt
* Add a maintainer's handbook to document KVM x86 processes, preferred coding
style, testing expectations, etc.
* Misc cleanups, fixes and comments
Generic:
* Miscellaneous bugfixes and cleanups
Selftests:
* Generate dependency files so that partial rebuilds work as expected

docs: remove the tips on how to submit patches from MAINTAINERS
Having "how to submit patches" in MAINTAINTERS seems out of place. We have a whole section of documentation about it, duplication is harmful and a lot of the text looks really out of date. Sections 1, 2 and 4 look really, really old and not applicable to the modern process. Section 3 is obvious but also we have build bots now. Section 5 is a bit outdated (diff -u?!). But I like the part about factoring out shared code, so add that to process docs. Section 6 is unnecessary? Section 7 is covered by more appropriate docs.

ARM: New SoC support for 6.5
There are two new SoC families this time, and both appear fairly similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are both dual-core Cortex-A35 based chips for the low-power industrial embedded market, and they mark the first 64-bit product in a widely used family of 32-bit Arm MCUs and SoCs. The way into the kernel is completely different here: The team at ST has a long history of working upstream with their STM32MP1 and other SoCs, and they produced a complete port to arm64 together with the initial announcement. Nuvoton also has multiple SoC product lines with current or previous upstream support, but those are maintained by third parties and are unrelated. The patch series from Nuvoton's Jacky Huang had to go through many revisisions to get to this point and is still missing a few drivers including the serial port for the moment. The branch contains the devicetree files as well as all the code changes, in order to have something that can be tested standalone. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmScqtkACgkQYKtH/8kJ Uifqyg//XgvZBxb/2GILYcThVgLoo1fYA9tG5M0LERY/aPiUwrCwIl5swGQXK4vK E3UBLsQURer4yEBRq7iB6RGbwa4Opjdy3yTkj6WSgEMPh6e6jGvmm+dJ7HuWeviS 8oeyo3Xar6tIF+A8xlBloHA4J6690FYB40McQzh8sWG5SE+id56S71NGnNW0kQTn wsul9BZcGVoyMYNBi/uXtOVUPy7jF3UBC3HJF9UOT7q77bCLjVc/aHmmnZ3zmbYA 2oX3X5hVJakFba6vnz+rjNlzuAoGXJPDdsKFxBysdsksac/TxqRIQGNe75DZZVgz ESTpt1QqjmCFw32HEzi8Ne22FOpzlBqUxBMznHPenpz1/om2ezs3q7ffuPqKvMaq PANuK++JKJaBChVMzJbn84Sr1fvO4ecGJpKZTFC6t6SqHQNQFJT6rfMHx01Xw2wW LjKfEBCR6zEXN0+FaaujgJ4y/9pH1VHPynrZJG9WEwPUEZb2kJ/2RMXjNpzOWKiB pWYV1oW2TqFKYKhFm/pjkbi6Rq76UwEi8fWWoGMkmeV3KZ/0GFauQhItu6mX3s7W uGnUQyrBzWzUoashYFuNtXKHYdwuWgOmG660BXHkyxwvqV96ICGEJ+97zGIBDj81 F8zLxEjPbsEZqGGSosAyk9oYC6eh7eK2V7xx+CUYLTuKZw13zNo= =zaVi -----END PGP SIGNATURE----- Merge tag 'soc-newsoc-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull new ARM SoC support from Arnd Bergmann: "There are two new SoC families this time, and both appear fairly similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are both dual-core Cortex-A35 based chips for the low-power industrial embedded market, and they mark the first 64-bit product in a widely used family of 32-bit Arm MCUs and SoCs.

docs: handling-regressions: rework section about fixing procedures
This basically rewrites the 'Prioritize work on fixing regressions' section of Documentation/process/handling-regressions.rst for various reasons. Among them: some things were too demanding, some didn't align well with the usual workflows, and some apparently were not clear enough -- and of course a few things were missing that would be good to have in there. Linus for example recently stated that regressions introduced during the past year should be handled similarly to regressions from the current cycle, if it's a clear fix with no semantic subtlety. His exact wording[1] didn't fit well into the text structure, but the author tried to stick close to the apparent intention. It was a noble goal from the original author to state "[prevent situations that might force users to] continue running an outdated and thus potentially insecure kernel version for more than two weeks after a regression's culprit was identified"; this directly led to the goal "fix regression in mainline within one week, if the issue made it into a stable/longterm kernel", because the stable team needs time to pick up and prepare a new release. But apparently all that was a bit too demanding. That "one week" target for example doesn't align well with the usual habits of the subsystem maintainers, which normally send their fixes to Linus once a week; and it doesn't align too well with stable/longterm releases either, which often enter a -rc phase on Mondays or Tuesdays and then are released two to three days later. And asking developers to create, review, and mainline fixes within one week might be too much to ask for in general. Hence tone the general goal down to three weeks and use an approach that better aligns with the usual merging and release habits. While at it, also make the rules of thumb a bit easier to follow by grouping them by topic (e.g. generic things, timing, procedures, ...). Also add text for a few cases where recent discussions showed they need covering. Among them are multiple points that better explain the relations to stable and longterm kernels and the team that manages them; they and the group seperators are the primary reason why this whole section sadly grew somewhat in the rewrite. The group about those relations led to one addition the author came up with without any precedent from Linus: the text now tells developers to add a stable tag for any regression that made it into a proper mainline release during the past 12 months. This is meant to ensure the stable team will definitely notice any fixes for recent regressions. That includes those introduced shortly before a new mainline release and found right after it; without such a rule the stable team might miss the fix, which then would only reach users after weeks or months with later releases. Note, the aspect "Do not consider regressions from the current cycle as something that can wait till the cycle's end [...]" might look like an addition, but was kinda was in the old text as well -- but only indirectly. That apparently was too subtle, as many developers seem to assume waiting till the end of the cycle is fine (even for build fixes). In practice this was especially problematic when a cause of a regression made it into a proper release (either directly or through a backport). A revert performed by Linus shortly before the 6.3 release illustrated that[2], as the developer of the culprit had been willing to revert the culprit about three weeks earlier already -- but didn't do so when a fix came into sight and a maintainer suggested it can wait. Due to that the issue in the end plagued users of 6.2.y at least two weeks longer than necessary, as the fix in the end didn't become ready in time. This issue in fact could have been resolved one or two additional weeks earlier, if the developer had reverted the culprit shortly after it had been identified (which even the old version of the text suggest to do in such cases).

Documentation/process: add soc maintainer handbook
Arnd suggested that adding a maintainer handbook for the SoC "subsystem" would be helpful in trying to bring on board maintainers for the various new platforms cropping up in RISC-V land. Add a document briefly describing the role of the SoC subsystem and some basic advice for (new) platform maintainers.

rust: upgrade to Rust 1.68.2
This is the first upgrade to the Rust toolchain since the initial Rust
merge, from 1.62.0 to 1.68.2 (i.e. the latest).
# Context
The kernel currently supports only a single Rust version [1] (rather
than a minimum) given our usage of some "unstable" Rust features [2]
which do not promise backwards compatibility.
The goal is to reach a point where we can declare a minimum version for
the toolchain. For instance, by waiting for some of the features to be
stabilized. Therefore, the first minimum Rust version that the kernel
will support is "in the future".
# Upgrade policy
Given we will eventually need to reach that minimum version, it would be
ideal to upgrade the compiler from time to time to be as close as
possible to that goal and find any issues sooner. In the extreme, we
could upgrade as soon as a new Rust release is out. Of course, upgrading
so often is in stark contrast to what one normally would need for GCC
and LLVM, especially given the release schedule: 6 weeks for Rust vs.
half a year for LLVM and a year for GCC.
Having said that, there is no particular advantage to updating slowly
either: kernel developers in "stable" distributions are unlikely to be
able to use their distribution-provided Rust toolchain for the kernel
anyway [3]. Instead, by routinely upgrading to the latest instead,
kernel developers using Linux distributions that track the latest Rust
release may be able to use those rather than Rust-provided ones,
especially if their package manager allows to pin / hold back /
downgrade the version for some days during windows where the version may
not match. For instance, Arch, Fedora, Gentoo and openSUSE all provide
and track the latest version of Rust as they get released every 6 weeks.
Then, when the minimum version is reached, we will stop upgrading and
decide how wide the window of support will be. For instance, a year of
Rust versions. We will probably want to start small, and then widen it
over time, just like the kernel did originally for LLVM, see commit

Networking changes for 6.4.
Core
----
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances.
- Reduce compound page head access for zero-copy data transfers.
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
- Threaded NAPI improvements, adding defer skb free support and unneeded
softirq avoidance.
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking.
- Add lockless accesses annotation to sk_err[_soft].
- Optimize again the skb struct layout.
- Extends the skb drop reasons to make it usable by multiple
subsystems.
- Better const qualifier awareness for socket casts.
BPF
---
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and variable-sized
accesses.
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward.
- Add more precise memory usage reporting for all BPF map types.
- Adds support for using {FOU,GUE} encap with an ipip device operating
in collect_md mode and add a set of BPF kfuncs for controlling encap
params.
- Allow BPF programs to detect at load time whether a particular kfunc
exists or not, and also add support for this in light skeleton.
- Bigger batch of BPF verifier improvements to prepare for upcoming BPF
open-coded iterators allowing for less restrictive looping capabilities.
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
programs to NULL-check before passing such pointers into kfunc.
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
local storage maps.
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps.
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree.
- Add BPF verifier support for ST instructions in convert_ctx_access()
which will help new -mcpu=v4 clang flag to start emitting them.
- Add ARM32 USDT support to libbpf.
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations.
Protocols
---------
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address.
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
- Add the handshake upcall mechanism, allowing the user-space
to implement generic TLS handshake on kernel's behalf.
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures.
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers.
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction.
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore.
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter
---------
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged.
- Update bridge netfilter and ovs conntrack helpers to handle
IPv6 Jumbo packets properly, i.e. fetch the packet length
from hop-by-hop extension header. This is needed for BIT TCP
support.
- The iptables 32bit compat interface isn't compiled in by default
anymore.
- Move ip(6)tables builtin icmp matches to the udptcp one.
This has the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used.
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device.
Driver API
----------
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time.
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them.
- Allow the page_pool to directly recycle the pages from safely
localized NAPI.
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization.
- Add YNL support for user headers and struct attrs.
- Add partial YNL specification for devlink.
- Add partial YNL specification for ethtool.
- Add tc-mqprio and tc-taprio support for preemptible traffic classes.
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device.
- Add basic LED support for switch/phy.
- Add NAPI documentation, stop relaying on external links.
- Convert dsa_master_ioctl() to netdev notifier. This is a preparatory
work to make the hardware timestamping layer selectable by user
space.
- Add transceiver support and improve the error messages for CAN-FD
controllers.

Commit volume in documentation is relatively low this time, but there is
still a fair amount going on, including:
- Reorganizing the architecture-specific documentation under
Documentation/arch. This makes the structure match the source directory
and helps to clean up the mess that is the top-level Documentation
directory a bit. This work creates the new directory and moves x86 and
most of the less-active architectures there. The current plan is to move
the rest of the architectures in 6.5, with the patches going through the
appropriate subsystem trees.
- Some more Spanish translations and maintenance of the Italian
translation.
- A new "Kernel contribution maturity model" document from Ted.
- A new tutorial on quickly building a trimmed kernel from Thorsten.
Plus the usual set of updates and fixes.

Documentation/process: always CC responsible lists
The "Select the recipients for your patch" part about CC-ing mailing lists is a bit vague and might be understood that only some lists should be Cc-ed. That's not what most of the maintainers expect. For given code, associated mailing list must always be CC-ed, because the list is used for reviewing and testing patches. Example are the Devicetree bindings patches, which are tested iff Devicetree mailing list is CC-ed.

docs: process: allow Closes tags with links
Since v6.3, checkpatch.pl now complains about the use of "Closes:" tags
followed by a link [1]. It also complains if a "Reported-by:" tag is
followed by a "Closes:" one [2].
As detailed in the first patch, this "Closes:" tag is used for a bit of
time, mainly by DRM and MPTCP subsystems. It is used by some bug trackers
to automate the closure of issues when a patch is accepted. It is even
planned to use this tag with bugzilla.kernel.org [3].
The first patch updates the documentation to explain what is this
"Closes:" tag and how/when to use it. The second patch modifies
checkpatch.pl to stop complaining about it.
The DRM maintainers and their mailing list have been added in Cc as they
are probably interested by these two patches as well.
[1] https://lore.kernel.org/all/3b036087d80b8c0e07a46a1dbaaf4ad0d018f8d5.1674217480.git.linux@leemhuis.info/

[3] https://lore.kernel.org/linux-doc/20230315181205.f3av7h6owqzzw64p@meerkat.local/
This patch (of 5):
Making sure a bug tracker is up to date is not an easy task. For example,
a first version of a patch fixing a tracked issue can be sent a long time
after having created the issue. But also, it can take some time to have
this patch accepted upstream in its final form. When it is done, someone
-- probably not the person who accepted the patch -- has to remember about
closing the corresponding issue.
This task of closing and tracking the patch can be done automatically by
bug trackers like GitLab [1], GitHub [2] and hopefully soon [3]
bugzilla.kernel.org when the appropriated tag is used. The two first ones
accept multiple tags but it is probably better to pick one.

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.

char: pcmcia: remove all the drivers
These char PCMCIA drivers are buggy[1] and receive only minimal care. It was concluded[2], that we should try to remove most pcmcia drivers completely. Let's start with these char broken one. Note that I also removed a UAPI header: include/uapi/linux/cm4000_cs.h. I found only coccinelle tests mentioning some ioctl constants from that file. But they are not actually used. Anyway, should someone complain, we may reintroduce the header (or its parts).

Documentation: simplify and clarify DCO contribution example language
Long long ago, in a more innocent time, Greg wrote the clarification for
how the DCO should work and that you couldn't make anonymous
contributions, because the sign-off needed to be something we could
check back with.
It was 2006, and nobody reacted to the wording, the whole Facebook 'real
name' controversy was a decade in the future, and nobody even thought
about it. And despite the language, we've always accepted nicknames and
that language was never meant to be any kind of exclusionary wording.
In fact, even when it became a discussion in other adjacent projects,
apparently nobody even thought to just clarify the language in the
kernel docs, and instead we had projects like the CNCF that had long
discussions about it, and wrote their own clarifications [1] of it.
Just simplify the wording to the point where it shouldn't be causing

Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

docs: recommend using Link: whenever using Reported-by:
Encourage developers to place Link: tag pointing to the report when they are using Reported-by: tags. Those links are often extremely useful for any code archaeologist that wants to know more about the backstory of a change than the commit message provides. That includes maintainers higher up in the patch-flow hierarchy, which is why Linus asks developers to add such links [1, 2, 3]. To quote [1]: > Again, the commit has a link to the patch *submission*, which is > almost entirely useless. There's no link to the actual problem the > patch fixes. > > [...] > > Put another way: I can see that > > Reported-by: Zhangfei Gao <zhangfei.gao@foxmail.com> > > in the commit, but I don't have a clue what the actual report was, and > there really isn't enough information in the commit itself, except for > a fairly handwavy "Device drivers might, for instance, still need to > flush operations.." > > I don't want to know what device drivers _might_ do. I would want to > have an actual pointer to what they do and where. Another reason why these links are wanted: the ongoing regression tracking efforts can only scale with them, as they allow the regression tracking bot 'regzbot' to automatically connect tracked reports with patches that are posted or committed to fix tracked regressions.

docs: maintainer-pgp-guide: update for latest gnupg defaults
It is finally becoming increasingly rare to find a distribution that still ships with gnupg-1.x, so remove the last vestiges of "gpg" vs "gpg2" from documentation. Similarly, starting with GnuPG 2.2 and above, the default --gen-key operation creates ed25519/cv25519 keypairs, so update all example command outputs to use that combination instead of rsa2048. Lastly, add a few wording tweaks and remove links that lead to stale information (e.g. hardware tokens overview from 2017).

The length of the questions prevents readers from locating content that's relevant at a glance.

This was a not-too-busy cycle for documentation; highlights include:
- The beginnings of a set of translations into Spanish, headed up by Carlos
Bilbao.
- More Chinese translations.
- A change to the Sphinx "alabaster" theme by default for HTML generation.
Unlike the previous default (Read the Docs), alabaster is shipped with
Sphinx by default, reducing the number of other dependencies that need to
be installed. It also (IMO) produces a cleaner and more readable result.
- The ability to render the documentation into the texinfo format
(something Sphinx could always do, we just never wired it up until now).
Plus the usual collection of typo fixes, build-warning fixes, and minor
updates.

Documentation: process: replace outdated LTS table w/ link
The existing table was a bit outdated. 3.16 was EOL in 2020. 4.4 was EOL in 2022. 5.10 is new in 2020. 5.15 is new in 2021. We'll see if 6.1 becomes LTS in 2022. Rather than keep this table updated, it does duplicate information from multiple kernel.org pages. Make one less duplication site that needs to be updated and simply refer to the kernel.org page on releases.

docs: netdev: offer performance feedback to contributors
Some of us gotten used to producing large quantities of peer feedback at work, every 3 or 6 months. Extending the same courtesy to community members seems like a logical step. It may be hard for some folks to get validation of how important their work is internally, especially at smaller companies which don't employ many kernel experts. The concept of "peer feedback" may be a hyperscaler / silicon valley thing so YMMV. Hopefully we can build more context as we go.

docs: bump minimal GNU Make version to 3.82
GNU Make 3.81 fails in CONFIG_RUST=y builds. rust/Makefile:105: *** multiple target patterns. Stop. make[1]: *** [prepare] Error 2 make: *** [__sub-make] Error 2 The error message is unclear, but the reason is because the 'private' keyword is only supported since GNU Make 3.82. GNU Make 3.81 is still able to build the kernel when CONFIG_RUST is disabled, but it might be a good timing to raise the minimal GNU Make version. Perhaps, I am the last person who was testing GNU Make 3.81. GNU Make 3.81 was released in 2006, GNU Make 3.82 in 2010.

hardening updates for v6.1-rc1
Various fixes across several hardening areas:
- loadpin: Fix verity target enforcement (Matthias Kaehlcke).
- zero-call-used-regs: Add missing clobbers in paravirt (Bill Wendling).
- CFI: clean up sparc function pointer type mismatches (Bart Van Assche).
- Clang: Adjust compiler flag detection for various Clang changes (Sami
Tolvanen, Kees Cook).
- fortify: Fix warnings in arch-specific code in sh, ARM, and xen.
Improvements to existing features:
- testing: improve overflow KUnit test, introduce fortify KUnit test,
add more coverage to LKDTM tests (Bart Van Assche, Kees Cook).
- overflow: Relax overflow type checking for wider utility.
New features:
- string: Introduce strtomem() and strtomem_pad() to fill a gap in
strncpy() replacement needs.
- um: Enable FORTIFY_SOURCE support.
- fortify: Enable run-time struct member memcpy() overflow warning.

Pull kernel hardening updates from Kees Cook:
"Most of the collected changes here are fixes across the tree for
various hardening features (details noted below).
The most notable new feature here is the addition of the memcpy()
overflow warning (under CONFIG_FORTIFY_SOURCE), which is the next step
on the path to killing the common class of "trivially detectable"
buffer overflow conditions (i.e. on arrays with sizes known at compile
time) that have resulted in many exploitable vulnerabilities over the
years (e.g. BleedingTooth).
This feature is expected to still have some undiscovered false
positives. It's been in -next for a full development cycle and all the
reported false positives have been fixed in their respective trees.
All the known-bad code patterns we could find with Coccinelle are also
either fixed in their respective trees or in flight.

Rust introduction for v6.1-rc1
The initial support of Rust-for-Linux comes in roughly 4 areas: - Kernel internals (kallsyms expansion for Rust symbols, %pA format) - Kbuild infrastructure (Rust build rules and support scripts) - Rust crates and bindings for initial minimum viable build - Rust kernel documentation and samples Rust support has been in linux-next for a year and a half now, and the short log doesn't do justice to the number of people who have contributed both to the Linux kernel side but also to the upstream Rust side to support the kernel's needs.

coding-style.rst: document BUG() and WARN() rules ("do not crash the kernel")
Linus notes [1] that the introduction of new code that uses VM_BUG_ON()
is just as bad as BUG_ON(), because it will crash the kernel on
distributions that enable CONFIG_DEBUG_VM (like Fedora):
VM_BUG_ON() has the exact same semantics as BUG_ON. It is literally
no different, the only difference is "we can make the code smaller
because these are less important". [2]
This resulted in a more generic discussion about usage of BUG() and
friends. While there might be corner cases that still deserve a BUG_ON(),
most BUG_ON() cases should simply use WARN_ON_ONCE() and implement a
recovery path if reasonable:
The only possible case where BUG_ON can validly be used is "I have
some fundamental data corruption and cannot possibly return an
error". [2]
As a very good approximation is the general rule:
"absolutely no new BUG_ON() calls _ever_" [2]
... not even if something really shouldn't ever happen and is merely for
documenting that an invariant always has to hold. However, there are sill
exceptions where BUG_ON() may be used:
If you have a "this is major internal corruption, there's no way we can
continue", then BUG_ON() is appropriate. [3]
There is only one good BUG_ON():
Now, that said, there is one very valid sub-form of BUG_ON():
BUILD_BUG_ON() is absolutely 100% fine. [2]
While WARN will also crash the machine with panic_on_warn set, that's
exactly to be expected:
So we have two very different cases: the "virtual machine with good
logging where a dead machine is fine" - use 'panic_on_warn'. And
the actual real hardware with real drivers, running real loads by
users. [4]
The basic idea is that warnings will similarly get reported by users
and be found during testing. However, in contrast to a BUG(), there is a
way to actually influence the expected behavior (e.g., panic_on_warn)
and to eventually keep the machine alive to extract some debug info.
Ingo notes that not all WARN_ON_ONCE cases need recovery. If we don't ever
expect this code to trigger in any case, recovery code is not really
helpful.
I'd prefer to keep all these warnings 'simple' - i.e. no attempted
recovery & control flow, unless we ever expect these to trigger.
[5]
There have been different rules floating around that were never properly
documented. Let's try to clarify.

docs: add Rust documentation
Most of the documentation for Rust is written within the source code itself, as it is idiomatic for Rust projects. This applies to both the shared infrastructure at `rust/` as well as any other Rust module (e.g. drivers) written across the kernel. However, these documents contain general information that does not fit particularly well in the source code, like the Quick Start guide. It also contains a few other small changes elsewhere in the documentation folder.
