Merge tag 'rust-6.6' of https://github.com/Rust-for-Linux/linux

Pull rust updates from Miguel Ojeda:
"In terms of lines, most changes this time are on the pinned-init API
and infrastructure. While we have a Rust version upgrade, and thus a
bunch of changes from the vendored 'alloc' crate as usual, this time
those do not account for many lines.

Toolchain and infrastructure:

- Upgrade to Rust 1.71.1. This is the second such upgrade, which is a
smaller jump compared to the last time.

This version allows us to remove the '__rust_*' allocator functions
-- the compiler now generates them as expected, thus now our
'KernelAllocator' is used.

It also introduces the 'offset_of!' macro in the standard library
(as an unstable feature) which we will need soon. So far, we were
using a declarative macro as a prerequisite in some not-yet-landed
patch series, which did not support sub-fields (i.e. nested
structs):

#[repr(C)]
struct S {
a: u16,
b: (u8, u8),
}

assert_eq!(offset_of!(S, b.1), 3);

- Upgrade to bindgen 0.65.1. This is the first time we upgrade its
version.

Given it is a fairly big jump, it comes with a fair number of
improvements/changes that affect us, such as a fix needed to
support LLVM 16 as well as proper support for '__noreturn' C
functions, which are now mapped to return the '!' type in Rust:

void __noreturn f(void); // C
pub fn f() -> !; // Rust

- 'scripts/rust_is_available.sh' improvements and fixes.

This series takes care of all the issues known so far and adds a
few new checks to cover for even more cases, plus adds some more
help texts. All this together will hopefully make problematic
setups easier to identify and to be solved by users building the
kernel.

In addition, it adds a test suite which covers all branches of the
shell script, as well as tests for the issues found so far.

- Support rust-analyzer for out-of-tree modules too.

- Give 'cfg's to rust-analyzer for the 'core' and 'alloc' crates.

- Drop 'scripts/is_rust_module.sh' since it is not needed anymore.

Macros crate:

- New 'paste!' proc macro.

This macro is a more flexible version of 'concat_idents!': it
allows the resulting identifier to be used to declare new items and
it allows to transform the identifiers before concatenating them,
e.g.

let x_1 = 42;
paste!(let [<x _2>] = [<x _1>];);
assert!(x_1 == x_2);

The macro is then used for several of the pinned-init API changes
in this pull.

Pinned-init API:

- Make '#[pin_data]' compatible with conditional compilation of
fields, allowing to write code like:

#[pin_data]
pub struct Foo {
#[cfg(CONFIG_BAR)]
a: Bar,
#[cfg(not(CONFIG_BAR))]
a: Baz,
}

- New '#[derive(Zeroable)]' proc macro for the 'Zeroable' trait,
which allows 'unsafe' implementations for structs where every field
implements the 'Zeroable' trait, e.g.:

#[derive(Zeroable)]
pub struct DriverData {
id: i64,
buf_ptr: *mut u8,
len: usize,
}

- Add '..Zeroable::zeroed()' syntax to the 'pin_init!' macro for
zeroing all other fields, e.g.:

pin_init!(Buf {
buf: [1; 64],
..Zeroable::zeroed()
});

- New '{,pin_}init_array_from_fn()' functions to create array
initializers given a generator function, e.g.:

let b: Box<[usize; 1_000]> = Box::init::<Error>(
init_array_from_fn(|i| i)
).unwrap();

assert_eq!(b.len(), 1_000);
assert_eq!(b[123], 123);

- New '{,pin_}chain' methods for '{,Pin}Init<T, E>' that allow to
execute a closure on the value directly after initialization, e.g.:

let foo = init!(Foo {
buf <- init::zeroed()
}).chain(|foo| {
foo.setup();
Ok(())
});

- Support arbitrary paths in init macros, instead of just identifiers
and generic types.

- Implement the 'Zeroable' trait for the 'UnsafeCell<T>' and
'Opaque<T>' types.

- Make initializer values inaccessible after initialization.

- Make guards in the init macros hygienic.

'allocator' module:

- Use 'krealloc_aligned()' in 'KernelAllocator::alloc' preventing
misaligned allocations when the Rust 1.71.1 upgrade is applied
later in this pull.

The equivalent fix for the previous compiler version (where
'KernelAllocator' is not yet used) was merged into 6.5 already,
which added the 'krealloc_aligned()' function used here.

- Implement 'KernelAllocator::{realloc, alloc_zeroed}' for
performance, using 'krealloc_aligned()' too, which forwards the
call to the C API.

'types' module:

- Make 'Opaque' be '!Unpin', removing the need to add a
'PhantomPinned' field to Rust structs that contain C structs which
must not be moved.

- Make 'Opaque' use 'UnsafeCell' as the outer type, rather than
inner.

Documentation:

- Suggest obtaining the source code of the Rust's 'core' library
using the tarball instead of the repository.

MAINTAINERS:

- Andreas and Alice, from Samsung and Google respectively, are
joining as reviewers of the "RUST" entry.

The current Kbuild does not require $(MODLIB)/source. If the kernel was
built in a separate output directory, $(MODLIB)/build/Makefile wraps
