Huacai et al.: I wonder if we could get this one into 6.12.y?

Maybe no one actually cares in practice, so please feel free to ignore
it, but it is the only `objtool` warning (a lot of instances, but just
that kind from a quick look) I have in my LoongArch Rust builds I have
in 6.12.y, and it would be nice to have it clean.

Thanks!

Cheers,
Miguel

I agree with you, it is better to backport to 6.12.y. But it needs
"LoongArch: Make LTO case independent in Makefile" as its dependency,
and need "LoongArch: Fix build error for LTO with LLVM-18" as a further
fix.
