I applied this series to your latest kbuild branch, built an Arch
Linux x86_64 config and Fedora aarch64 config with
CONFIG_LTO_CLANG_FULL=y then CONFIG_LTO_CLANG_THIN=y, and boot tested
each kernel in QEMU with a full userspace. I did not notice any new
warnings/errors and everything appears to work fine.

Cheers,
Nathan
