kernel-doc.rst has two 1st level section titles of "Writing kernel-doc comments" and "Including kernel-doc comments". Therefore, rather than using the first one, put a meta title of "Kernel-doc comments" for the title of the resulting HTML page by using the "title" directive.

With kernel releases v5.18 and later, if you have Inkscape, images embedded in PDF documents are of vector graphics, not the raster images as are the case with pre-v5.18 releases. Even with pre-5.18 releases, having Inkscape would improve images converted from some of SVG files which are not fully covered by the limited capability of rsvg-convert(1) [1]. Add a footnote mentioning the expected improvements of such images.

Some warnings do not increment the warnings counter making the behavior of running kernel-doc with -Werror unlogical as some warnings will be generated but not treated as errors. Fix this by creating a helper function that always incrementing the warnings counter every time a warning is emitted. There is one location in get_sphinx_version() where a warning is not touched as it concerns the execution environment of the kernel-doc and not the documentation being processed. Incrementing the counter only have effect when running kernel-doc in either verbose mode (-v or environment variable KBUILD_VERBOSE) or when treating warnings as errors (-Werror or environment variable KDOC_WERROR). In both cases the number of warnings printed is printed to stderr and for the later the exit code of kernel-doc is non-zero if warnings where encountered. Simple test case to demo one of the warnings, $ cat test.c /** * foo() - Description */ int bar(); # Without this change $ ./scripts/kernel-doc -Werror -none test.c test.c:4: warning: expecting prototype for foo(). Prototype was for bar() instead # With this change $ ./scripts/kernel-doc -Werror -none test.c test.c:4: warning: expecting prototype for foo(). Prototype was for bar() instead 1 warnings as Errors Signed-off-by: Niklas Söderlund <niklas.soderlund@corigine.com> Link: https://lore.kernel.org/r/20220613090510.3088294-1-niklas.soderlund@corigine.comSigned-off-by: Jonathan Corbet <corbet@lwn.net>

Pull random number generator fixes from Jason Donenfeld: - A fix for a 5.19 regression for a case in which early device tree initializes the RNG, which flips a static branch. On most plaforms, jump labels aren't initialized until much later, so this caused splats. On a few mailing list threads, we cooked up easy fixes for arm64, arm32, and risc-v. But then things looked slightly more involved for xtensa, powerpc, arc, and mips. And at that point, when we're patching 7 architectures in a place before the console is even available, it seems like the cost/risk just wasn't worth it. So random.c works around it now by checking the already exported `static_key_initialized` boolean, as though somebody already ran into this issue in the past. I'm not super jazzed about that; it'd be prettier to not have to complicate downstream code. But I suppose it's practical. - A few small code nits and adding a missing __init annotation. - A change to the default config values to use the cpu and bootloader's seeds for initializing the RNG earlier. This brings them into line with what all the distros do (Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at least), and moreover will now give us test coverage in various test beds that might have caught the above device tree bug earlier. - A change to WireGuard CI's configuration to increase test coverage around the RNG. - A documentation comment fix to unrelated maintainerless CRC code that I was asked to take, I guess because it has to do with polynomials (which the RNG thankfully no longer uses). * tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: wireguard: selftests: use maximum cpu features and allow rng seeding random: remove rng_has_arch_random() random: credit cpu and bootloader seeds by default random: do not use jump labels before they are initialized random: account for arch randomness in bits random: mark bootloader randomness code as __init random: avoid checking crng_ready() twice in random_init() crc-itu-t: fix typo in CRC ITU-T polynomial comment

WMI queries fail on some devices where the ACPI method HWMC unconditionally attempts to create Fields beyond the buffer if the buffer is too small, this breaks essential features such as power profiles: CreateByteField (Arg1, 0x10, D008) CreateByteField (Arg1, 0x11, D009) CreateByteField (Arg1, 0x12, D010) CreateDWordField (Arg1, 0x10, D032) CreateField (Arg1, 0x80, 0x0400, D128) In cases where args->data had zero length, ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit offset/length 128/8 exceeds size of target Buffer (128 bits) (20211217/dsopcode-198) was obtained. ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit offset/length 136/8 exceeds size of target Buffer (136bits) (20211217/dsopcode-198) The original code created a buffer size of 128 bytes regardless if the WMI call required a smaller buffer or not. This particular behavior occurs in older BIOS and reproduced in OMEN laptops. Newer BIOS handles buffer sizes properly and meets the latest specification requirements. This is the reason why testing with a dynamically allocated buffer did not uncover any failures with the test systems at hand. This patch was tested on several OMEN, Elite, and Zbooks. It was confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN Laptop 15-ek0xxx. No problems were reported when testing on several Elite and Zbooks notebooks.
