Thank you for this! I built+booted(under emulation) arm64 defconfig and built arm64 allmodconfig with LLVM=1 with this series applied.
Tested-by: Nick Desaulniers <ndesaulniers@google.com>
One thing I noticed was a spew of warnings for allmodconfig, like: init/main.o: warning: objtool: asan.module_ctor()+0xc: call without frame pointer save/setup init/main.o: warning: objtool: asan.module_dtor()+0xc: call without frame pointer save/setup
I assume those are from the KASAN constructors. See also: https://github.com/ClangBuiltLinux/linux/issues/1238
Can we disable HAVE_STACK_PROTECTOR if CC_IS_CLANG and CONFIG_KASAN is set, until we can resolve the above issue?
