Merge tag 'rust-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux

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

- Enable a set of Clippy lints: 'ptr_as_ptr', 'ptr_cast_constness',
'as_ptr_cast_mut', 'as_underscore', 'cast_lossless' and
'ref_as_ptr'

These are intended to avoid type casts with the 'as' operator,
which are quite powerful, into restricted variants that are less
powerful and thus should help to avoid mistakes

- Remove the 'author' key now that most instances were moved to the
plural one in the previous cycle

'kernel' crate:

- New 'bug' module: add 'warn_on!' macro which reuses the existing
'BUG'/'WARN' infrastructure, i.e. it respects the usual sysctls and
kernel parameters:

warn_on!(value == 42);

To avoid duplicating the assembly code, the same strategy is
followed as for the static branch code in order to share the
assembly between both C and Rust

This required a few rearrangements on C arch headers -- the
existing C macros should still generate the same outputs, thus no
functional change expected there

- 'workqueue' module: add delayed work items, including a
'DelayedWork' struct, a 'impl_has_delayed_work!' macro and an
'enqueue_delayed' method, e.g.:

/// Enqueue the struct for execution on the system workqueue,
/// where its value will be printed 42 jiffies later.
fn print_later(value: Arc<MyStruct>) {
let _ = workqueue::system().enqueue_delayed(value, 42);
}

- New 'bits' module: add support for 'bit' and 'genmask' functions,
with runtime- and compile-time variants, e.g.:

static_assert!(0b00010000 == bit_u8(4));
static_assert!(0b00011110 == genmask_u8(1..=4));

assert!(checked_bit_u32(u32::BITS).is_none());

- 'uaccess' module: add 'UserSliceReader::strcpy_into_buf', which
reads NUL-terminated strings from userspace into a '&CStr'

Introduce 'UserPtr' newtype, similar in purpose to '__user' in C,
to minimize mistakes handling userspace pointers, including mixing
them up with integers and leaking them via the 'Debug' trait. Add
it to the prelude, too

- Start preparations for the replacement of our custom 'CStr' type
with the analogous type in the 'core' standard library. This will
take place across several cycles to make it easier. For this one,
it includes a new 'fmt' module, using upstream method names and
some other cleanups

Replace 'fmt!' with a re-export, which helps Clippy lint properly,
and clean up the found 'uninlined-format-args' instances

- 'dma' module:

- Clarify wording and be consistent in 'coherent' nomenclature

- Convert the 'read!()' and 'write!()' macros to return a 'Result'

- Add 'as_slice()', 'write()' methods in 'CoherentAllocation'

- Expose 'count()' and 'size()' in 'CoherentAllocation' and add
the corresponding type invariants

- Implement 'CoherentAllocation::dma_handle_with_offset()'

- 'time' module:

- Make 'Instant' generic over clock source. This allows the
compiler to assert that arithmetic expressions involving the
'Instant' use 'Instants' based on the same clock source

- Make 'HrTimer' generic over the timer mode. 'HrTimer' timers
take a 'Duration' or an 'Instant' when setting the expiry time,
depending on the timer mode. With this change, the compiler can
check the type matches the timer mode

- Add an abstraction for 'fsleep'. 'fsleep' is a flexible sleep
function that will select an appropriate sleep method depending
on the requested sleep time

- Avoid 64-bit divisions on 32-bit hardware when calculating
timestamps

- Seal the 'HrTimerMode' trait. This prevents users of the
'HrTimerMode' from implementing the trait on their own types

- Pass the correct timer mode ID to 'hrtimer_start_range_ns()'

- 'list' module: remove 'OFFSET' constants, allowing to remove
pointer arithmetic; now 'impl_list_item!' invokes
'impl_has_list_links!' or 'impl_has_list_links_self_ptr!'. Other
simplifications too

- 'types' module: remove 'ForeignOwnable::PointedTo' in favor of a
constant, which avoids exposing the type of the opaque pointer, and
require 'into_foreign' to return non-null

Remove the 'Either<L, R>' type as well. It is unused, and we want
to encourage the use of custom enums for concrete use cases

- 'sync' module: implement 'Borrow' and 'BorrowMut' for 'Arc' types
to allow them to be used in generic APIs

- 'alloc' module: implement 'Borrow' and 'BorrowMut' for 'Box<T, A>';
and 'Borrow', 'BorrowMut' and 'Default' for 'Vec<T, A>'

- 'Opaque' type: add 'cast_from' method to perform a restricted cast
that cannot change the inner type and use it in callers of
'container_of!'. Rename 'raw_get' to 'cast_into' to match it

- 'rbtree' module: add 'is_empty' method

- 'sync' module: new 'aref' submodule to hold 'AlwaysRefCounted' and
'ARef', which are moved from the too general 'types' module which
we want to reduce or eventually remove. Also fix a safety comment
in 'static_lock_class'

'pin-init' crate:

- Add 'impl<T, E> [Pin]Init<T, E> for Result<T, E>', so results are
now (pin-)initializers

- Add 'Zeroable::init_zeroed()' that delegates to 'init_zeroed()'

- New 'zeroed()', a safe version of 'mem::zeroed()' and also provide
it via 'Zeroable::zeroed()'

- Implement 'Zeroable' for 'Option<&T>', 'Option<&mut T>' and for
'Option<[unsafe] [extern "abi"] fn(...args...) -> ret>' for
'"Rust"' and '"C"' ABIs and up to 20 arguments

- Changed blanket impls of 'Init' and 'PinInit' from 'impl<T, E>
[Pin]Init<T, E> for T' to 'impl<T> [Pin]Init<T> for T'

- Renamed 'zeroed()' to 'init_zeroed()'

- Upstream dev news: improve CI more to deny warnings, use
'--all-targets'. Check the synchronization status of the two
'-next' branches in upstream and the kernel

MAINTAINERS:

- Add Vlastimil Babka, Liam R. Howlett, Uladzislau Rezki and Lorenzo
Stoakes as reviewers (thanks everyone)

rust: enable `clippy::cast_lossless` lint

Before Rust 1.29.0, Clippy introduced the `cast_lossless` lint [1]:

> Rust’s `as` keyword will perform many kinds of conversions, including
> silently lossy conversions. Conversion functions such as `i32::from`
> will only perform lossless conversions. Using the conversion functions
> prevents conversions from becoming silently lossy if the input types
> ever change, and makes it clear for people reading the code that the
> conversion is lossless.

While this doesn't eliminate unchecked `as` conversions, it makes such
conversions easier to scrutinize. It also has the slight benefit of
removing a degree of freedom on which to bikeshed. Thus apply the
changes and enable the lint -- no functional change intended.

gpu: nova-core: update and annotate TODO list

A few new dependencies are required to remove some of the TODO items:

- A way to safely convert from byte slices to types implementing
`FromBytes`,
- A way to obtain slices and write into a `CoherentAllocation`,
- Several improvements to the `register!()` macro,
- Alignment operations to powers of two, and an equivalent to the C
`fls`,
- Support for `xa_alloc` in the XAlloc bindings.

Some items have also become obsolete:

- The auxiliary bus abstractions have been implemented and are in use,
- The ELF utilities are not considered for being part of the core kernel
bindings anymore.
- VBIOS, falcon and GPU timer have been completed.

We now have quite a few TODO entries in the code, so annotate them with
a 4 letter code representing the corresponding task in `todo.rst`. This
allows to easily find which part of the code corresponds to a given
entry (and conversely).

Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.

The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw
interfaces.

There is also the introduction of an asahi uapi header file as a
precursor to getting the real driver in later, but to unblock
userspace mesa packages while the driver is trapped behind rust
enablement.

Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,

gpu: nova-core: define registers layout using helper macro

Add the register!() macro, which defines a given register's layout and
provide bit-field accessors with a way to convert them to a given type.
This macro will allow us to make clear definitions of the registers and
manipulate their fields safely.

The long-term goal is to eventually move it to the kernel crate so it
can be used by other drivers as well, but it was agreed to first land it
into nova-core and make it mature there.

To illustrate its usage, use it to define the layout for the Boot0
(renamed to NV_PMC_BOOT_0 to match OpenRM's naming scheme) and take
advantage of its accessors.
