Subject: [GIT PULL] Rust for 6.7

Hi Linus,

This is the next round of the Rust support.

The majority of the commits have been in linux-next for 10+ days.
The younger ones have been there for 3 rounds now.

No conflicts expected. No changes to the C side.

There are also some Rust workqueue abstractions which you will likely
get through the wq tree. No conflicts expected with those either, and
tests pass with those merged too.

Please pull for v6.7 -- thanks!

Cheers,
Miguel

  docs: rust: add "The Rust experiment" section (2023-10-25 03:14:00 +0200)

----------------------------------------------------------------
Rust changes for v6.7

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.
