Also, I see Nathan sent meanwhile a message about these two that were
also mentioned/reported a while ago [1].

On my side, I noticed these due to my loongarch64 defconfig
compile-test with Rust enabled yesterday [2], but I don't want to step
on Tom/Colin/Nathan/ClangBuiltLinux's work, so please feel free to do
with these patches as you will!

Thanks!
