I agree: let's exclude this patch from -stable.

While the CFLAGS part of it is still _technically_ valid without Rust,
it turns out it triggers a bug in gcc <11, so is probably best
avoided. See:
- https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99652
- https://lore.kernel.org/linux-um/20230318041555.4192172-1-davidgow@google.com/

Cheers,
