Hi Greg, Sasha,

Please consider applying the following commits for 6.13.y:

27c7518e7f1c ("rust: finish using custom FFI integer types")
1bae8729e50a ("rust: map `long` to `isize` and `char` to `u8`")
9b98be76855f ("rust: cleanup unnecessary casts")

They should apply cleanly.

This backports the custom FFI integer types, which in turn solves a build failure under `CONFIG_RUST_FW_LOADER_ABSTRACTIONS=y`.

I will have to send something similar to 6.12.y, but it requires more commits -- I may do the `alloc` backport first we discussed the other day.

Hi Miguel,

Has anything come of these 6.12.y backports? It sounds like we're otherwise about to have to disable features in NixOS's default kernel due to build regressions with Rust 1.85.0.
