Linux kernel patches Miscellaneous fixes and improvements: These are fixes and improvements that don’t fit into a particular category but are important to ClangBuiltLinux. scripts/Makefile.extrawarn: Do not disable clang's -Wformat-zero-length (v1) x86/build: Move '-mindirect-branch-cs-prefix' out of GCC-only block (v1) Stable backport requests: It is important to make sure that the stable trees are as free from issues as possible, as those are the trees that devices and users use; for example, Android and Chrome OS regularly merge from stable, so if there is a problem that will impact those trees that we fixed in mainline, it should be backported....

Linux kernel patches Android changes: Android is one of the largest downstream consumers of our work. Our continuous integeration tests the Android trees with newer versions of LLVM to help catch any issues that will impact Android once they upgrade their version of LLVM, which can lag behind at times....

Recently, I started exploring setting up a self-hosted GitHub Actions runner for the work-in-progress LLVM builds that ClangBuiltLinux is looking to distribute on kernel.org, as GitHub Actions hosted runners are pretty underwhelming in terms of performance and we want to soup these builds up with Profile Guided Optimization. Additionallly, GitHub Actions does not have a hosted arm64 Linux option, which is becoming increasingly important with chips such as Apple’s M1 getting strong mainline Linux support....

Occasionally, compiling the Linux kernel with a new compiler flag will result in a boot failure. If you are lucky, there will be some output to the serial console but that may not happen if the issue happens in early boot code before the serial driver has loaded. When this happens, it usually requires building part of the kernel without the compiler flag (or the “negative” version of it) to try and figure out the exact translation unit and function that causes the problem....
