rust: uapi: Add UAPI crate This crate mirrors the `bindings` crate, but will contain only UAPI bindings. Unlike the bindings crate, drivers may directly use this crate if they have to interface with userspace. Initially, just bind the generic ioctl stuff. In the future, we would also like to add additional checks to ensure that all types exposed by this crate satisfy UAPI-safety guarantees (that is, they are safely castable to/from a "bag of bits"). [ Miguel: added support for the `rustdoc` and `rusttest` targets, since otherwise they fail, and we want to keep them working. ] Reviewed-by: Martin Rodriguez Reboredo <yakoyoku@gmail.com> Signed-off-by: Asahi Lina <lina@asahilina.net> Link: https://lore.kernel.org/r/20230329-rust-uapi-v2-1-bca5fb4d4a12@asahilina.net Signed-off-by: Miguel Ojeda <ojeda@kernel.org>

rust: allow `dead_code` for never constructed bindings Starting with the upcoming Rust 1.80.0 (since upstream commit 35130d7233e9 ("Detect pub structs never constructed and unused associated constants in traits")), the `dead_code` pass detects more cases, which triggers in the `bindings` crate: warning: struct `boot_params` is never constructed --> rust/bindings/bindings_generated.rs:10684:12 | 10684 | pub struct boot_params { | ^^^^^^^^^^^ | = note: `#[warn(dead_code)]` on by default As well as in the `uapi` one: warning: struct `boot_params` is never constructed --> rust/uapi/uapi_generated.rs:10392:12 | 10392 | pub struct boot_params { | ^^^^^^^^^^^ | = note: `#[warn(dead_code)]` on by default These are all expected, since we do not use all the structs in the bindings that `bindgen` generates from the C headers. Therefore, allow them.
