[GIT PULL] Rust for v6.9

[GIT PULL] Rust for v6.9

[Miguel Ojeda]

Hi Linus,

This is the next round of the Rust support.

All the commits have been in linux-next for more than a week.

A small conflict with the arm64 pull expected, as well as a trivial one
with the mm-nonmm. Both are resolved in linux-next in the rust-next
merge. No changes to the C side.

You will likely get Rust support for arm64, the first kselftest for Rust
and a couple improvements for Rust net PHY through their respective
trees as well. LoongArch, RISC-V and VFS pull requests could carry
something too, but probably on the next one.

Please pull for v6.9 -- thanks!

Cheers,
Miguel

  rust: upgrade to Rust 1.76.0 (2024-02-29 22:18:05 +0100)

----------------------------------------------------------------
Rust changes for v6.9

Another routine one in terms of features. We got two version upgrades
this time, but in terms of lines, 'alloc' changes are not very large.

Toolchain and infrastructure:

 - Upgrade to Rust 1.76.0.

   This time around, due to how the kernel and Rust schedules have
   aligned, there are two upgrades in fact. These allow us to remove two
   more unstable features ('const_maybe_uninit_zeroed' and
   'ptr_metadata') from the list, among other improvements.

 - Mark 'rustc' (and others) invocations as recursive, which fixes a new
   warning and prepares us for the future in case we eventually take
   advantage of the Make jobserver.

'kernel' crate:

 - Add the 'container_of!' macro.

 - Stop using the unstable 'ptr_metadata' feature by employing the now
   stable 'byte_sub' method to implement 'Arc::from_raw()'.

 - Add the 'time' module with a 'msecs_to_jiffies()' conversion function
   to begin with, to be used by Rust Binder.

 - Add 'notify_sync()' and 'wait_interruptible_timeout()' methods to
   'CondVar', to be used by Rust Binder.

 - Update integer types for 'CondVar'.

 - Rename 'wait_list' field to 'wait_queue_head' in 'CondVar'.

 - Implement 'Display' and 'Debug' for 'BStr'.

 - Add the 'try_from_foreign()' method to the 'ForeignOwnable' trait.

 - Add reexports for macros so that they can be used from the right
   module (in addition to the root).

 - A series of code documentation improvements, including adding
   intra-doc links, consistency improvements, typo fixes...

'macros' crate:

 - Place generated 'init_module()' function in '.init.text'.

Documentation:

 - Add documentation on Rust doctests and how they work.
