Pull drm fixes from Dave Airlie:
"The weekly drm fixes. This is mostly msm fixes across the functions,
with amdgpu and i915. It also has a core rust fix and changes in
nova-core to take advantage of it, and otherwise just has some minor
driver fixes, and marks loongsoon as orphaned.

rust:
- Fix safety issue in dma_read! and dma_write!

nova-core:
- Fix UB in DmaGspMem pointer accessors
- Fix stack overflow in GSP memory allocation

loongsoon:
- mark drm driver as unmaintained

msm:
- Core:
- Adjusted msm_iommu_pagetable_prealloc_allocate() allocation type
- DPU:
- Fixed blue screens on Hamoa laptops by reverting the LM
reservation
- Fixed the size of the LM block on several platforms
- Dropped usage of %pK (again)
- Fixed smatch warning on SSPP v13+ code
- Fixed INTF_6 interrupts on Lemans
- DSI:
- Fixed DSI PHY revision on Kaanapali
- Fixed pixel clock calculation for the bonded DSI mode panels
with compression enabled
- DT bindings:
- Fixed DisplayPort description on Glymur
- Fixed model name in SM8750 MDSS schema
- GPU:
- Added MODULE_DEVICE_TABLE to the GPU driver
- Fix bogus protect error on X2-85
- Fix dma_free_attrs() buffer size
- Gen8 UBWC fix for Glymur

i915:
- Avoid hang when configuring VRR [icl]
- Fix sg_table overflow with >4GB folios
- Fix PSR Selective Update handling
- Fix eDP ALPM read-out sequence

amdgpu:
- SMU13 fix
- SMU14 fix
- Fixes for bringup hw testing
- Kerneldoc fix
- GC12 idle power fix for compute workloads
- DCCG fixes

amdkfd:
- Fix missing BO unreserve in an error path

ivpu:
- drop unnecessary bootparams register setting

amdxdna:
- fix runtime/suspend resume deadlock

bridge:
- ti-sn65dsi83: fix DSI rounding and dual LVDS

gud:
- fix NULL crtc dereference on display disable"

rust: ptr: add projection infrastructure

Add a generic infrastructure for performing field and index projections on
raw pointers. This will form the basis of performing I/O projections.

Pointers manipulations are intentionally using the safe wrapping variants
instead of the unsafe variants, as the latter requires pointers to be
inside an allocation which is not necessarily true for I/O pointers.

This projection macro protects against rogue `Deref` implementation, which
can causes the projected pointer to be outside the bounds of starting
pointer. This is extremely unlikely and Rust has a lint to catch this, but
is unsoundness regardless. The protection works by inducing type inference
ambiguity when `Deref` is implemented.

This projection macro also stops projecting into unaligned fields (i.e.
fields of `#[repr(packed)]` structs), as misaligned pointers require
special handling. This is implemented by attempting to create reference to
projected field inside a `if false` block. Despite being unreachable, Rust
still checks that they're not unaligned fields.

The projection macro supports both fallible and infallible index
projections. These are described in detail inside the documentation.

[ * Add intro-doc links where possible,
* Fix typos and slightly improve wording, e.g. "as documentation
describes" -> "as the documentation of [`Self::proj`] describes",
* Add an empty line between regular and safety comments, before
examples, and between logically independent comments,
* Capitalize various safety comments.
