riscv patches for 6.16-rc1, part 2

* Performance improvements
- Add support for vdso getrandom
- Implement raid6 calculations using vectors
- Introduce svinval tlb invalidation

* Cleanup
- A bunch of deduplication of the macros we use for manipulating instructions

* Misc
- Introduce a kunit test for kprobes
- Add support for mseal as riscv fits the requirements (thanks to Lorenzo for making sure of that :))

[Palmer: There was a rebase between part 1 and part 2, so I've had to do
some more git surgery here... at least two rounds of surgery...]

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
Tegra264, Richtek ALC203 and RT9123 and Rockchip SAI controllers.

rust: clean Rust 1.88.0's `clippy::uninlined_format_args` lint

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);
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#uninlined_format_args

|
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.

Merge tag 'rust-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux

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

- Extract the 'pin-init' API from the 'kernel' crate and make it into
a standalone crate.

In order to do this, the contents are rearranged so that they can
easily be kept in sync with the version maintained out-of-tree that
other projects have started to use too (or plan to, like QEMU).

This will reduce the maintenance burden for Benno, who will now
have his own sub-tree, and will simplify future expected changes
like the move to use 'syn' to simplify the implementation.

- Add '#[test]'-like support based on KUnit.

We already had doctests support based on KUnit, which takes the
examples in our Rust documentation and runs them under KUnit.

Now, we are adding the beginning of the support for "normal" tests,
similar to those the '#[test]' tests in userspace Rust. For
instance:

#[kunit_tests(my_suite)]
mod tests {
#[test]
fn my_test() {
assert_eq!(1 + 1, 2);
}
}

Unlike with doctests, the 'assert*!'s do not map to the KUnit
assertion APIs yet.

- Check Rust signatures at compile time for functions called from C
by name.

In particular, introduce a new '#[export]' macro that can be placed
in the Rust function definition. It will ensure that the function
declaration on the C side matches the signature on the Rust
function:

#[export]
pub unsafe extern "C" fn my_function(a: u8, b: i32) -> usize {
// ...
}

The macro essentially forces the compiler to compare the types of
the actual Rust function and the 'bindgen'-processed C signature.

These cases are rare so far. In the future, we may consider
introducing another tool, 'cbindgen', to generate C headers
automatically. Even then, having these functions explicitly marked
may be a good idea anyway.

- Enable the 'raw_ref_op' Rust feature: it is already stable, and
allows us to use the new '&raw' syntax, avoiding a couple macros.
After everyone has migrated, we will disallow the macros.

- Pass the correct target to 'bindgen' on Usermode Linux.

- Fix 'rusttest' build in macOS.

'kernel' crate:

- New 'hrtimer' module: add support for setting 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.

- New 'dma' module: add a simple DMA coherent allocator abstraction
and a test sample driver.

- 'list' module: make the linked list 'Cursor' point between
elements, rather than at an element, which is more convenient to us
and allows for cursors to empty lists; and document it with
examples of how to perform common operations with the provided
methods.

- 'str' module: implement a few traits for 'BStr' as well as the
'strip_prefix()' method.

- 'sync' module: add 'Arc::as_ptr'.

- 'alloc' module: add 'Box::into_pin'.

- 'error' module: extend the 'Result' documentation, including a few
examples on different ways of handling errors, a warning about
using methods that may panic, and links to external documentation.

'macros' crate:

- 'module' macro: add the 'authors' key to support multiple authors.
The original key will be kept until everyone has migrated.

Documentation:

- Add error handling sections.

MAINTAINERS:

- Add Danilo Krummrich as reviewer of the Rust "subsystem".

- Add 'RUST [PIN-INIT]' entry with Benno Lossin as maintainer. It has
its own sub-tree.

- Add sub-tree for 'RUST [ALLOC]'.

- Add 'DMA MAPPING HELPERS DEVICE DRIVER API [RUST]' entry with
Abdiel Janulgue as primary maintainer. It will go through the
sub-tree of the 'RUST [ALLOC]' entry.

- Add 'HIGH-RESOLUTION TIMERS [RUST]' entry with Andreas Hindborg as
maintainer. It has its own sub-tree.

And a few other cleanups and improvements"

rust: pin-init: internal: synchronize with user-space version

Synchronize the internal macros crate with the user-space version that
uses the quote crate [1] instead of a custom `quote!` macro. The imports
in the different version are achieved using `cfg` on the kernel config
value. This cfg is always set in the kernel and never set in the
user-space version.

Since the quote crate requires the proc_macro2 crate, imports also need
to be adjusted and `.into()` calls have to be inserted.
