Boot-tested under QEMU for Rust x86_64, arm64 and riscv64:

In loongarch64 I am seeing:

    arch/loongarch/mm/tlb.c:292:19: error: use of undeclared identifier 'exception_handlers'; did you mean 'exception_table'?
      292 |                 vec_sz = sizeof(exception_handlers);

And then the many missing safety comments Clippy warnings we expected,
i.e. the ones that we discussed recently, e.g.:

    warning: unsafe block missing a safety comment
        --> rust/kernel/init/macros.rs:1015:25

I hope this helps!
