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"
