Sorry, I may not have made it clear. I mean all these changes.

I had some contributions in rust-lang/rust repo for riscv64 (PR #131955, 
FWIW), and I'd like to be added as a Rust + RISC-V Linux maintainer if 
that's okay for you guys.

For the suggestions about commit messages, I will improve them in the 
next revision.

Thanks for your reviews!
