Merge tag 'rust-6.7' of https://github.com/Rust-for-Linux/linux
Pull rust updates from Miguel Ojeda: "A small one compared to the previous one in terms of features. In terms of lines, as usual, the 'alloc' version upgrade accounts for most of them. Toolchain and infrastructure: - Upgrade to Rust 1.73.0 This time around, due to how the kernel and Rust schedules have aligned, there are two upgrades in fact. They contain the fixes for a few issues we reported to the Rust project. In addition, a few cleanups indicated by the upgraded compiler or possible thanks to it. For instance, the compiler now detects redundant explicit links. - A couple changes to the Rust 'Makefile' so that it can be used with toybox tools, allowing Rust to be used in the Android kernel build. x86: - Enable IBT if enabled in C Documentation: - Add "The Rust experiment" section to the Rust index page MAINTAINERS: - Add Maintainer Entry Profile field ('P:'). - Update our 'W:' field to point to the webpage we have been building this year" * tag 'rust-6.7' of https://github.com/Rust-for-Linux/linux: docs: rust: add "The Rust experiment" section x86: Enable IBT in Rust if enabled in C rust: Use grep -Ev rather than relying on GNU grep rust: Use awk instead of recent xargs rust: upgrade to Rust 1.73.0 rust: print: use explicit link in documentation rust: task: remove redundant explicit link rust: kernel: remove `#[allow(clippy::new_ret_no_self)]` MAINTAINERS: add Maintainer Entry Profile field for Rust MAINTAINERS: update Rust webpage rust: upgrade to Rust 1.72.1 rust: arc: add explicit `drop()` around `Box::from_raw()`

+The Rust experiment
+-------------------
+
+The Rust support was merged in v6.1 into mainline in order to help in
+determining whether Rust as a language was suitable for the kernel, i.e. worth
+the tradeoffs.
+
+Currently, the Rust support is primarily intended for kernel developers and
+maintainers interested in the Rust support, so that they can start working on
+abstractions and drivers, as well as helping the development of infrastructure
+and tools.
+
+If you are an end user, please note that there are currently no in-tree
+drivers/modules suitable or intended for production use, and that the Rust
+support is still in development/experimental, especially for certain kernel
+configurations.
