Here's a patch updating the meaning of TAINT_CPU_OUT_OF_SPEC after Borislav introduced changes in a7e1f67e and upcoming patches in tip. TAINT_CPU_OUT_OF_SPEC now means a bit more what it implies as the flag isn't set just because of a CPU misconfiguration or mismatch. Historically it was for SMP kernel oops on an officially SMP incapable processor but now it also covers CPUs whose MSRs have been incorrectly poked at from userspace, drivers being used on non supported architectures, broken firmware, mismatched CPUs, ... Update documentation and script to reflect that. Signed-off-by:

Make various places which point to Documentation/admin-guide/reporting-bugs.rst point to Documentation/admin-guide/reporting-issues.rst instead. That document is brand new and as of now is not completely finished. But even at this stage it's a lot more helpful and accurate than reporting-bugs.rst. Hence also add a note to reporting-bugs.rst, telling people they're better off reading reporting-issues.rst instead. reporting-bugs.rst is scheduled for removal once reporting-issues.rst is considered ready.

Add a mostly finished document describing how to report issues with the Linux kernel to its developers. It is designed to be a lot more straight forward and easier to follow than the current text about this (Documentation/admin-guide/reporting-bugs.rst); at the same time the new text should be more helpful for people unfamiliar with the topic, as it provides a lot more details, too. The main work on the text is done, but some polishing is still needed. The text also needs to be reviewed by more people and a few issues still might need some discussion. To make these tasks easier, it was decided ([1]) to add this document to the kernel sources in parallel to the existing text; the latter will be removed once this text is considered good enough(tm). This document is quite long and provides a lot of details, but was carefully crafted to make sure it's can also serve people that are in a hurry. That's mainly achieved by having a TDLR and a step-by-step guide, which should be good enough for quite a lot of people. Everybody that wants or need more explanations can find them in a reference section, which describes all the needed steps in detail. Thanks to this structure the text can work for kernel developers that just need to look something up, experienced FLOSS contributors that are unfamiliar with the kernel's bug reporting workflow, and users reporting something upstream for the first time. The text is thus a bit like the kernel itself, which works well for embedded machines, a typical desktop PC, cloud servers, and HPC. The document was written in the hope it will improve the quality of the bug reports, especially those that come from people unfamiliar with how Linux kernel development works. Sadly quite a few reports from this group are currently of poor quality and/or get submitted to the wrong place. Part of the problem is the old reporting-bugs document, as it makes its essence hard to grasp; it's and also inaccurate and slightly outdated in a few spots. Due to this quite a few valid reports are ignored in the end, which is annoying for those that compiled them and bad for the kernel's quality. The document near the top points out that it's still unfinished, but nevertheless ready for consumption. Those few areas in the text that might need some further discussion contain a note pointing this out. Besides lack of review from core developers there is only one major issue left: the section 'Decode failure message' is known to be outdated: it's waiting for someone familiar with the topic to write something up or give at least provide some hints and pointers what to write there. The new document is dual-licensed under GPL-2.0+ or CC-BY-4.0. The latter is way more liberal and makes it attractive to use this text as a base when writing about this topic on websites or in books. This hopefully increases the chances that such texts are accurate and stick to official way of doing things. [1] https://lkml.kernel.org/r/20201118172958.5b014a44@lwn.netSigned-off-by:

Add the full text of the CC-BY-4.0 license to the kernel tree as well as the required tags for reference and tooling. The license text was copied directly from the following url, but for clarification a 'Creative Commons' was added before 'Attribution 4.0 International' in the first line: https://creativecommons.org/licenses/by/4.0/legalcode.txt CC-BY-4.0 is GPLv2 compatible, but when for example used for the kernel's documentation it can easily happen that sphinx during processing combines it with text or code from files using a more restrictive license[1]. This bears pitfalls, hence point that risk out and suggest to only use this license in combination with the GPLv2. [1] https://lkml.kernel.org/r/20201201144314.GA14256@lst.deSigned-off-by:

Changeset 6b80975c ("scripts: kernel-doc: fix typedef parsing") added support for things like: typedef unsigned long foo(); However, it caused a regression on this prototype: typedef bool v4l2_check_dv_timings_fnc(const struct v4l2_dv_timings *t, void *handle); This is only noticed after adding a patch that checks if the kernel-doc identifier matches the typedef: ./scripts/kernel-doc -none $(git grep '^.. kernel-doc::' Documentation/ |cut -d ' ' -f 3|sort|uniq) 2>&1|grep expecting include/media/v4l2-dv-timings.h:38: warning: expecting prototype for typedef v4l2_check_dv_timings_fnc. Prototype was for typedef nc instead The problem is that, with the new parsing logic, it is not checking for complete words at the type part. Fix it by adding a \b at the end of each type word at the regex. fixes: 6b80975c ("scripts: kernel-doc: fix typedef parsing") Signed-off-by:

Add support for the same output format as the bash script, and use its implementation instead of the previous one. I opted to do such patch in order to have a single script responsible for parsing Documentation/features and produce different outputs. As someone may rely on the past format, which is easy to parse it, get_feat.pl now gains a new command with the same output format as the previous script. As a side effect, the perl script is a lot faster, as it reads each file only once, instead of parsing files several times via a for command and grep commands inside it. This patch also changes the features list order to be case-insensitive, in order to better match the output of the existing script. Signed-off-by:

The Documentation/features contains a set of parseable files. It is not worth converting them to ReST format, as they're useful the way it is. It is, however, interesting to parse them and produce output on different formats: 1) Output the contents of a feature in ReST format; 2) Output what features a given architecture supports; 3) Output a matrix with features x architectures.

Sphinx 3.1 introduced namespaces for C cross-references. With this, each C domain type/function declaration is put inside the namespace that was active at the time of its declaration. Add support for automatic cross-referencing inside C namespaces by checking whether the corresponding source file had a C namespace Sphinx directive, and if so, try cross-referencing inside of it before going to the global scope. This assumes there's only one namespace (if any) per rst file. Signed-off-by:
