I should've mentioned this patch is for 4.19 only as the code has been rewritten in later versions, but requires a large amount of backports (https://github.com/ClangBuiltLinux/linux/issues/1349). This is the only blocker for 4.19 migration to LLVM's integrated assembler on CrOS that I am aware of.
