Dave Airlie 9bdbf7eb25 DRM Rust changes for v7.1-rc1
- DMA:
   - Rework the DMA coherent API: introduce Coherent<T> as a generalized
     container for arbitrary types, replacing the slice-only
     CoherentAllocation<T>. Add CoherentBox for memory initialization
     before exposing a buffer to hardware (converting to Coherent when
     ready), and CoherentHandle for allocations without kernel mapping.
 
   - Add Coherent::init() / init_with_attrs() for one-shot initialization
     via pin-init, and from-slice constructors for both Coherent and
     CoherentBox
 
   - Add uaccess write_dma() for copying from DMA buffers to userspace
     and BinaryWriter support for Coherent<T>
 
 - DRM:
   - Add GPU buddy allocator abstraction
 
   - Add DRM shmem GEM helper abstraction
 
   - Allow drm::Device to dispatch work and delayed work items to driver
     private data
 
   - Add impl_aref_for_gem_obj!() macro to reduce GEM refcount
     boilerplate, and introduce DriverObject::Args for constructor
     context
 
   - Add dma_resv_lock helper and raw_dma_resv() accessor on GEM objects
 
   - Clean up imports across the DRM module
 
 - I/O:
   - Merged via a signed tag from the driver-core tree: register!() macro
     and I/O infrastructure improvements (IoCapable refactor, RelaxedMmio
     wrapper, IoLoc trait, generic accessors, write_reg /
     LocatedRegister)
 
 - Nova (Core):
   - Fix and harden the GSP command queue: correct write pointer
     advancing, empty slot handling, and ring buffer indexing; add mutex
     locking and make Cmdq a pinned type; distinguish wait vs no-wait
     commands
 
   - Add support for large RPCs via continuation records, splitting
     oversized commands across multiple queue slots
 
   - Simplify GSP sequencer and message handling code: remove unused
     trait and Display impls, derive Debug and Zeroable where applicable,
     warn on unconsumed message data
 
   - Refactor Falcon firmware handling: create DMA objects lazily, add
     PIO upload support, and use the Generic Bootloader to boot FWSEC on
     Turing
 
   - Convert all register definitions (PMC, PBUS, PFB, GC6, FUSE, PDISP,
     Falcon) to the kernel register!() macro; add bounded_enum macro to
     define enums usable as register fields
 
   - Migrate all DMA usage to the new Coherent, CoherentBox, and
     CoherentHandle APIs
 
   - Harden firmware parsing with checked arithmetic throughout FWSEC,
     Booter, RISC-V parsing paths
 
   - Add debugfs support for reading GSP-RM log buffers; replace
     module_pci_driver!() with explicit module init to support
     module-level debugfs setup
 
   - Fix auxiliary device registration for multi-GPU systems
 
   - Various cleanups: import style, firmware parsing refactoring,
     framebuffer size logging
 
 - Rust:
   - Add interop::list module providing a C linked list interface
 
   - Extend num::Bounded with shift operations, into_bool(), and const
     get() to support register bitfield manipulation
 
   - Enable the generic_arg_infer Rust feature and add EMSGSIZE error
     code
 
 - Tyr:
   - Adopt vertical import style per kernel Rust guidelines
 
   - Clarify driver/device type names and use DRM device type alias
     consistently across the driver
 
   - Fix GPU model/version decoding in GpuInfo
 
 - Workqueue:
   - Add ARef<T> support for work and delayed work
