ARC processors are supported in upstream kernel since v3.9 and so far there was no documentation about them except some Device Tree bindings. Fixing it with the simples set of docs now: 1. Overview with pointers to other informational resources 2. Autogenerated feature table Note though it's just the very beginning, there will be more for sure given time as there're many things worth documenting and in fact even contents itself is avaialble but just spread in some other places. Now we'll try to keep all here and then maintain it looking forward to match the state of development. Signed-off-by:

While node-states-8.dot has two digraphs, the dot(1) command can not properly handle multiple graphs in a DOT file and the kernel-doc page at https://www.kernel.org/doc/html/latest/admin-guide/blockdev/drbd/figures.html fails to render the graphs. It turned out that the digraph of node_states can be removed. Quote from Joel's reflection: On reflection, the digraph node_states can be removed entirely. It is too basic to contain any useful information. In addition it references "ioctl_set_state". The ioctl configuration interface for DRBD has long been removed. In fact, it was never in the upstream version of DRBD. Remove node_states and rename the DOT file peer_states-8.dot. Suggested-by:Joel Colledge <joel.colledge@linbit.com> Acked-by:

As described at: https://stackoverflow.com/questions/23211695/modifying-content-width-of-the-sphinx-theme-read-the-docs since Sphinx 1.8, the standard way to setup a custom theme is to use html_css_files. While using html_context is OK with RTD 0.5.2, it doesn't work with 1.0.0, causing the theme to not load, producing a very weird html. Tested with: - Sphinx 1.7.9 + sphinx-rtd-theme 0.5.2 - Sphinx 2.4.4 + sphinx-rtd-theme 0.5.2 - Sphinx 2.4.4 + sphinx-rtd-theme 1.0.0 - Sphinx 4.3.0 + sphinx-rtd-theme 1.0.0 Reported-by:

The cross-reference for the handbooks section works. However, it is meant to describe the path inside the Kernel's doc where the section is, but there's an space instead of a dash, plus it lacks the .rst at the end, which makes: ./scripts/documentation-file-ref-check to complain.

Add Kconfig support for -Wimplicit-fallthrough for both GCC and Clang. The compiler option is under configuration CC_IMPLICIT_FALLTHROUGH, which is enabled by default. Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This bugfix only appears in Clang 14.0.0, so older versions still contain the bug and -Wimplicit-fallthrough won't be enabled for them, for now. This concludes a long journey and now we are finally getting rid of the unintentional fallthrough bug-class in the kernel, entirely. :) Link: https://github.com/llvm/llvm-project/commit/9ed4a94d6451046a51ef393cd62f00710820a7e8 [1] Link: https://bugs.llvm.org/show_bug.cgi?id=51094 [2] Link: https://github.com/KSPP/linux/issues/115 Link: https://github.com/ClangBuiltLinux/linux/issues/236 Co-developed-by:
