Merge tag 'rust-hrtimer-for-v6.15-v3' of https://github.com/Rust-for-Linux/linux into rust-next

Pull rust-hrtimer updates from Andreas Hindborg:
"Introduce Rust support for the 'hrtimer' subsystem:

- Add a way to use the 'hrtimer' subsystem from Rust. Rust code can
now set up intrusive timers without allocating when starting the
timer.

- Add support for 'Pin<Box<_>>', 'Arc<_>', 'Pin<&_>' and
'Pin<&mut _>' as pointer types for use with timer callbacks.

- Add support for setting clock source and timer mode.

'kernel' crate:

- Add 'Arc::as_ptr' for converting an 'Arc' to a raw pointer. This is
a dependency for the 'hrtimer' API.

- Add 'Box::into_pin' for converting a 'Box<_>' into a 'Pin<Box<_>>'
to align with Rust 'alloc'. This is a dependency for the 'hrtimer'
API."
