Debian Trixie was released with a Rust 1.85.0 toolchain [2], which it still uses to this day [3] (i.e. no update to Rust 1.85.1). Debian Trixie's release happened on 2025-08-09 [4], which means that a fair amount of time has passed since its release for kernel developers to upgrade. Thus bump the minimum to the new version. Then, in later commits, clean up most of the workarounds and other bits that this upgrade of the minimum allows us. pin-init was left as-is since the patches come from upstream. And the vendored crates are unmodified, since we do not want to change those. Note that the minimum LLVM major version for Rust 1.85.0 is LLVM 18 (the Rust upstream binaries use LLVM 19.1.7), thus e.g. `RUSTC_LLVM_VERSION` tests can also be updated, but there are no suitable ones to simplify. Ubuntu 25.10 also has a recent enough Rust toolchain [5], and they also provide versioned packages with a Rust 1.85.1 toolchain even back to Ubuntu 22.04 LTS [6].
