Merge tag 'rust-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux

Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:

- KUnit '#[test]'s:

- Support KUnit-mapped 'assert!' macros.

The support that landed last cycle was very basic, and the
'assert!' macros panicked since they were the standard library
ones. Now, they are mapped to the KUnit ones in a similar way to
how is done for doctests, reusing the infrastructure there.

With this, a failing test like:

#[test]
fn my_first_test() {
assert_eq!(42, 43);
}

will report:

# my_first_test: ASSERTION FAILED at rust/kernel/lib.rs:251
Expected 42 == 43 to be true, but is false
# my_first_test.speed: normal
not ok 1 my_first_test

- Support tests with checked 'Result' return types.

The return value of test functions that return a 'Result' will
be checked, thus one can now easily catch errors when e.g. using
the '?' operator in tests.

With this, a failing test like:

#[test]
fn my_test() -> Result {
f()?;
Ok(())
}

will report:

# my_test: ASSERTION FAILED at rust/kernel/lib.rs:321
Expected is_test_result_ok(my_test()) to be true, but is false
# my_test.speed: normal
not ok 1 my_test

- Add 'kunit_tests' to the prelude.

- Clarify the remaining language unstable features in use.

- Compile 'core' with edition 2024 for Rust >= 1.87.

- Workaround 'bindgen' issue with forward references to 'enum' types.

- objtool: relax slice condition to cover more 'noreturn' functions.

- Use absolute paths in macros referencing 'core' and 'kernel'
crates.

- Skip '-mno-fdpic' flag for bindgen in GCC 32-bit arm builds.

- Clean some 'doc_markdown' lint hits -- we may enable it later on.

'kernel' crate:

- 'alloc' module:

- 'Box': support for type coercion, e.g. 'Box<T>' to 'Box<dyn U>'
if 'T' implements 'U'.

- 'Vec': implement new methods (prerequisites for nova-core and
binder): 'truncate', 'resize', 'clear', 'pop',
'push_within_capacity' (with new error type 'PushError'),
'drain_all', 'retain', 'remove' (with new error type
'RemoveError'), insert_within_capacity' (with new error type
'InsertError').

In addition, simplify 'push' using 'spare_capacity_mut', split
'set_len' into 'inc_len' and 'dec_len', add type invariant 'len
<= capacity' and simplify 'truncate' using 'dec_len'.

- 'time' module:

- Morph the Rust hrtimer subsystem into the Rust timekeeping
subsystem, covering delay, sleep, timekeeping, timers. This new
subsystem has all the relevant timekeeping C maintainers listed
in the entry.

- Replace 'Ktime' with 'Delta' and 'Instant' types to represent a
duration of time and a point in time.

- Temporarily add 'Ktime' to 'hrtimer' module to allow 'hrtimer'
to delay converting to 'Instant' and 'Delta'.

- 'xarray' module:

- Add a Rust abstraction for the 'xarray' data structure. This
abstraction allows Rust code to leverage the 'xarray' to store
types that implement 'ForeignOwnable'. This support is a
dependency for memory backing feature of the Rust null block
driver, which is waiting to be merged.

- Set up an entry in 'MAINTAINERS' for the XArray Rust support.
Patches will go to the new Rust XArray tree and then via the
Rust subsystem tree for now.

- Allow 'ForeignOwnable' to carry information about the pointed-to
type. This helps asserting alignment requirements for the
pointer passed to the foreign language.

- 'container_of!': retain pointer mut-ness and add a compile-time
check of the type of the first parameter ('$field_ptr').

- Support optional message in 'static_assert!'.

- Add C FFI types (e.g. 'c_int') to the prelude.

- 'str' module: simplify KUnit tests 'format!' macro, convert
'rusttest' tests into KUnit, take advantage of the '-> Result'
support in KUnit '#[test]'s.

- 'list' module: add examples for 'List', fix path of
'assert_pinned!' (so far unused macro rule).

- 'workqueue' module: remove 'HasWork::OFFSET'.

- 'page' module: add 'inline' attribute.

'macros' crate:

- 'module' macro: place 'cleanup_module()' in '.exit.text' section.

'pin-init' crate:

- Add 'Wrapper<T>' trait for creating pin-initializers for wrapper
structs with a structurally pinned value such as 'UnsafeCell<T>' or
'MaybeUninit<T>'.

- Add 'MaybeZeroable' derive macro to try to derive 'Zeroable', but
not error if not all fields implement it. This is needed to derive
'Zeroable' for all bindgen-generated structs.

- Add 'unsafe fn cast_[pin_]init()' functions to unsafely change the
initialized type of an initializer. These are utilized by the
'Wrapper<T>' implementations.

- Add support for visibility in 'Zeroable' derive macro.

- Add support for 'union's in 'Zeroable' derive macro.

- Upstream dev news: streamline CI, fix some bugs. Add new workflows
to check if the user-space version and the one in the kernel tree
have diverged. Use the issues tab [1] to track them, which should
help folks report and diagnose issues w.r.t. 'pin-init' better.

[1] https://github.com/rust-for-linux/pin-init/issues

Documentation:

- Testing: add docs on the new KUnit '#[test]' tests.

- Coding guidelines: explain that '///' vs. '//' applies to private
items too. Add section on C FFI types.

- Quick Start guide: update Ubuntu instructions and split them into
"25.04" and "24.04 LTS and older".

And a few other cleanups and improvements"

rust: kunit: support checked `-> Result`s in KUnit `#[test]`s

Currently, return values of KUnit `#[test]` functions are ignored.

Thus introduce support for `-> Result` functions by checking their
returned values.

At the same time, require that test functions return `()` or `Result<T,
E>`, which should avoid mistakes, especially with non-`#[must_use]`
types. Other types can be supported in the future if needed.

With this, a failing test like:

#[test]
fn my_test() -> Result {
f()?;
Ok(())
}

will output:

rust: kunit: support KUnit-mapped `assert!` macros in `#[test]`s

The KUnit `#[test]` support that landed recently is very basic and does
not map the `assert*!` macros into KUnit like the doctests do, so they
panic at the moment.

Thus implement the custom mapping in a similar way to doctests, reusing
the infrastructure there.

In Rust 1.88.0, the `file()` method in `Span` may be stable [1]. However,
it was changed recently (from `SourceFile`), so we need to do something
different in previous versions. Thus create a helper for it and use it
to get the path.

With this, a failing test suite like:

#[kunit_tests(my_test_suite)]
mod tests {
use super::*;

#[test]
fn my_first_test() {
assert_eq!(42, 43);
}

#[test]
fn my_second_test() {
assert!(42 >= 43);
}
}

will properly map back to KUnit, printing something like:

[ 1.924325] KTAP version 1
[ 1.924421] # Subtest: my_test_suite
[ 1.924506] # speed: normal

rust: use absolute paths in macros referencing core and kernel

Macros and auto-generated code should use absolute paths, `::core::...`
and `::kernel::...`, for core and kernel references.

This prevents issues where user-defined modules named `core` or `kernel`
could be picked up instead of the `core` or `kernel` crates.

Thus clean some references up.

ASoC: Updates for v6.16

The changes in this release are quite large, mainly in drivers rather
than the core. This is partly due to cleanups that touch a lot of
drivers and partly due to several relatively large new drivers.

- Support for automatically enumerating DAIs from standards conforming
SoundWire SDCA devices, further work is required for these to be
useful in an actual card.
- Conversion of quite a few drivers to newer GPIO APIs.
- More helpers and cleanups from Mormimoto-san.
- Support for a wider range of AVS platforms.
- Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32,
Everest Semiconductor ES8389, Longsoon-1 AC'97 controllers, nVidia

Starting with Rust 1.88.0 (expected 2025-06-26) [1], `rustc` may move
back the `uninlined_format_args` to `style` from `pedantic` (it was
there waiting for rust-analyzer suppotr), and thus we will start to see
lints like:

warning: variables can be used directly in the `format!` string
--> rust/macros/kunit.rs:105:37
|
105 | let kunit_wrapper_fn_name = format!("kunit_rust_wrapper_{}", test);

105 - let kunit_wrapper_fn_name = format!("kunit_rust_wrapper_{}", test);
105 + let kunit_wrapper_fn_name = format!("kunit_rust_wrapper_{test}");

There is even a case that is a pure removal:

warning: variables can be used directly in the `format!` string
--> rust/macros/module.rs:51:13

51 | format!("{field}={content}\0", field = field, content = content)

help: change this to
|
51 - format!("{field}={content}\0", field = field, content = content)
51 + format!("{field}={content}\0")

The lints all seem like nice cleanups, thus just apply them.

We may want to disable `allow-mixed-uninlined-format-args` in the future.
