2020-05-31checkpatch/coding-style: deprecate 80-column warningJoe Perches
Yes, staying withing 80 columns is certainly still _preferred_. But it's not the hard limit that the checkpatch warnings imply, and other concerns can most certainly dominate. Increase the default limit to 100 characters. Not because 100 characters is some hard limit either, but that's certainly a "what are you doing" kind of value and less likely to be about the occasional slightly longer lines. Miscellanea: - to avoid unnecessary whitespace changes in files, checkpatch will no longer emit a warning about line length when scanning files unless --strict is also used - Add a bit to coding-style about alignment to open parenthesis Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

An x86-64 defconfig will fail with Invalid absolute R_X86_64_32S relocation: _etext and after fixing that one, with Invalid absolute R_X86_64_32S relocation: __end_of_kernel_reserve Those two versions of binutils have a bug when it comes to handling symbols defined outside of a section and binutils 2.23 has the proper fix, see: https://sourceware.org/legacy-ml/binutils/2012-06/msg00155.html Therefore, up to the fixed version directly, skipping the broken ones.

2020-03-20docs: deprecated.rst: Add BUG()-familyKees Cook
Linus continues to remind[1] people to stop using the BUG()-family of functions. We should have this better documented (even if checkpatch.pl has been warning[2] since 2015), so add more details to deprecated.rst, as a distinct place to point people to for guidance.

2020-02-19Documentation: bring process docs up to dateTony Fischetti
The guide to the kernel dev process documentation, for example, contains references to older kernels and their timelines. In addition, one of the "long term support kernels" listed have since reached EOL, and a new one has been named. This patch brings information/tables up to date. Additionally, some very trivial grammatical errors, unclear sentences, and potentially unsavory diction have been edited.

2020-01-04Documentation: riscv: add patch acceptance guidelinesPaul Walmsley
Formalize, in kernel documentation, the patch acceptance policy for arch/riscv. In summary, it states that as maintainers, we plan to only accept patches for new modules or extensions that have been frozen or ratified by the RISC-V Foundation. We've been following these guidelines for the past few months. In the meantime, we've received quite a bit of feedback that it would be helpful to have these guidelines formally documented. Based on a suggestion from Matthew Wilcox, we also add a link to this file to Documentation/process/index.rst, to make this document easier to find. The format of this document has also been changed to align to the format outlined in the maintainer entry profiles, in accordance with comments from Jon Corbet and Dan Williams.
