I found this over the weekend myself and reverted the problematic commit in LLVM and I will make sure that if it lands again, it can build a kernel without any issues. https://github.com/llvm/llvm-project/commit/22eb1dae3fb20ca8ada865de1d95baab0e08a060 For the future, you may consider only sending reports of compiler crashes to Nick, myself, and llvm@lists.linux.dev; a compiler crash is pretty much never the fault of the source code so CC'ing Linux maintainers is just noise.
