Merge tag 'rust-6.5' of https://github.com/Rust-for-Linux/linux

Pull rust updates from Miguel Ojeda:
"A fairly small one in terms of feature additions. Most of the changes
in terms of lines come from the upgrade to the new version of the
toolchain (which in turn is big due to the vendored 'alloc' crate).

Upgrade to Rust 1.68.2:

- This is the first such upgrade, and we will try to update it often
from now on, in order to remain close to the latest release, until
a minimum version (which is "in the future") can be established.

The upgrade brings the stabilization of 4 features we used (and 2
more that we used in our old 'rust' branch).

Commit 3ed03f4da06e ("rust: upgrade to Rust 1.68.2") contains the
details and rationale.

pin-init API:

- Several internal improvements and fixes to the pin-init API, e.g.
allowing to use 'Self' in a struct definition with '#[pin_data]'.

'error' module:

- New 'name()' method for the 'Error' type (with 'errname()'
integration), used to implement the 'Debug' trait for 'Error'.

- Add error codes from 'include/linux/errno.h' to the list of Rust
'Error' constants.

- Allow specifying error type on the 'Result' type (with the default
still being our usual 'Error' type).

'str' module:

- 'TryFrom' implementation for 'CStr', and new 'to_cstring()' method
based on it.

'sync' module:

- Implement 'AsRef' trait for 'Arc', allowing to use 'Arc' in code
that is generic over smart pointer types.

- Add 'ptr_eq' method to 'Arc' for easier, less error prone
comparison between two 'Arc' pointers.

- Reword the 'Send' safety comment for 'Arc', and avoid referencing
it from the 'Sync' one.

'task' module:

- Implement 'Send' marker for 'Task'.

'types' module:

- Implement 'Send' and 'Sync' markers for 'ARef<T>' when 'T' is
'AlwaysRefCounted', 'Send' and 'Sync'.

Other changes:

- Documentation improvements and '.gitattributes' change to start
using the Rust diff driver"

Merge tag 'rust-6.4' of https://github.com/Rust-for-Linux/linux

Pull rust updates from Miguel Ojeda
"More additions to the Rust core. Importantly, this adds the pin-init
API, which will be used by other abstractions, such as the
synchronization ones added here too:

- pin-init API: a solution for the safe pinned initialization
problem.

This allows to reduce the need for 'unsafe' code in the kernel when
dealing with data structures that require a stable address. Commit
90e53c5e70a6 ("rust: add pin-init API core") contains a nice
introduction -- here is an example of how it looks like:

#[pin_data]
struct Example {
#[pin]
value: Mutex<u32>,

#[pin]
value_changed: CondVar,
}

impl Example {
fn new() -> impl PinInit<Self> {
pin_init!(Self {
value <- new_mutex!(0),
value_changed <- new_condvar!(),
})
}
}

// In a `Box`.
let b = Box::pin_init(Example::new())?;

// In the stack.
stack_pin_init!(let s = Example::new());

- 'sync' module:

New types 'LockClassKey' ('struct lock_class_key'), 'Lock',
'Guard', 'Mutex' ('struct mutex'), 'SpinLock' ('spinlock_t'),
'LockedBy' and 'CondVar' (uses 'wait_queue_head_t'), plus macros
such as 'static_lock_class!' and 'new_spinlock!'.

In particular, 'Lock' and 'Guard' are generic implementations that
contain code that is common to all locks. Then, different backends
(the new 'Backend' trait) are implemented and used to define types
like 'Mutex':

type Mutex<T> = Lock<T, MutexBackend>;

In addition, new methods 'assume_init()', 'init_with()' and
'pin_init_with()' for 'UniqueArc<MaybeUninit<T>>' and 'downcast()'
for 'Arc<dyn Any + Send + Sync>'; as well as 'Debug' and 'Display'
implementations for 'Arc' and 'UniqueArc'. Reduced stack usage of
'UniqueArc::try_new_uninit()', too.

- 'types' module:

New trait 'AlwaysRefCounted' and new type 'ARef' (an owned
reference to an always-reference-counted object, meant to be used
in wrappers for C types that have their own ref counting
functions).

Moreover, new associated functions 'raw_get()' and 'ffi_init()' for
'Opaque'.

- New 'task' module with a new type 'Task' ('struct task_struct'),
and a new macro 'current!' to safely get a reference to the current
one.

- New 'ioctl' module with new '_IOC*' const functions (equivalent to
the C macros).

- New 'uapi' crate, intended to be accessible by drivers directly.

- 'macros' crate: new 'quote!' macro (similar to the one provided in
userspace by the 'quote' crate); and the 'module!' macro now allows
specifying multiple module aliases.

- 'error' module:

New associated functions for the 'Error' type, such as
'from_errno()' and new functions such as 'to_result()'.

- 'alloc' crate:

More fallible 'Vec' methods: 'try_resize` and
'try_extend_from_slice' and the infrastructure (imported from the
Rust standard library) they need"

rust: macros: Allow specifying multiple module aliases

Modules can (and usually do) have multiple alias tags, in order to
specify multiple possible device matches for autoloading. Allow this by
changing the alias ModuleInfo field to an Option<Vec<String>>.

Note: For normal device IDs this is autogenerated by modpost (which is
not properly integrated with Rust support yet), so it is useful to be
able to manually add device match aliases for now, and should still be
useful in the future for corner cases that modpost does not handle.

This pulls in the expect_group() helper from the rfl/rust branch
(with credit to authors).
