Hi!

This is the start of the stable review cycle for the 6.12.81 release.
As far as I can tell, this is rc2, not a start of the review.
CIP testing did not find any problems here. 6.18 and 6.19 rc2's seem to be okay, too.

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);
| ^~~~~~~~~~~~~~~~~~

./arch/loongarch/include/asm/exception.h:9:14: note: 'exception_table' declared here
9 | extern void *exception_table[];
| ^
arch/loongarch/mm/tlb.c:292:18: error: invalid application of 'sizeof' to an incomplete type 'void *[]'
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!
