Merge tag 'drm-rust-next-2025-11-18' of https://gitlab.freedesktop.org/drm/rust/kernel into drm-next

Cross-subsystem Changes:

Rust
  - Make slice::as_flattened usable on all supported versions of rustc.
  - Add FromBytes::from_bytes_prefix() method.

Core Changes:

  - Update Tyr in MAINTAINERS file.
  - Remove redundant device ptr from Rust GEM object.
  - Change how AlwaysRefCounted is implemented for GEM objects.
  - Add deferred vm_bo cleanup to GPUVM and use it in Panthor.

Driver Changes:

Nova Core
  - Introduction of bitfield! macro, with support for different storage sizes
    and custom visibility.
  - Introduction of safe converters between integer types for which the
    conversion is lossless.
  - GSP initialized up to fully booted state on Ampere.
  - Use more future-proof register for GPU identification.
  - Various simplifications and optimizations.

Nova
  - Select NOVA_CORE.
  - Depend on CONFIG_64BIT.

-Conversion from byte slices for types implementing FromBytes [TRSM]
--------------------------------------------------------------------
-
-We retrieve several structures from byte streams coming from the BIOS or loaded
-firmware. At the moment converting the bytes slice into the proper type require
-an inelegant `unsafe` operation; this will go away once `FromBytes` implements
-a proper `from_bytes` method.

-CoherentAllocation improvements [COHA]
---------------------------------------
-
-`CoherentAllocation` needs a safe way to write into the allocation, and to
-obtain slices within the allocation.
