42cbb68ce8 drm/amdgpu: remove the ring param from ttm functions
With the removal of the direct_submit argument, the ring param
becomes useless: the jobs are always submitted to buffer_funcs_ring.

Some functions are getting an amdgpu_device argument since they
were getting it from the ring arg.

v4: remove adev param from amdgpu_ttm_map_buffer

e1b385726f drm/amd/display: Add additional checks for PSP footer size

Newer ASICs have different PSP footer sizes which lead to driver
failing to locate the DMCUB FW meta info, which in turn causes
improper DMCUB FW loading and causes DMCUB to crash.

as well.

- Do not add padding when computing PPS values, and instead track padding
  separately to add when calculating slice width values

a574f53ed5 drm/amd/display: Permit DC_FP_START/END only in non-FP compilation units
[WHAT]
Test the existing CPP macro _LINUX_FPU_COMPILATION_UNIT, which is set
when building source files that are permitted to use floating point,
in the implementation of DC_FP_START/END so that those are only usable
in non-FP code. This is a requirement of the generic kernel mode FPU
API, as some architectures (i.e., arm64) cannot safely enable FP codegen
in arbitrary code.

2634ef1b8c drm/amdkfd: Fix PTE clearing during SVM unmap on GFX 12.1
During migration from VRAM to RAM, when PTE is cleared, reset
the PTE to always ensure that PTE.P=1 is set on GFX 12.1. If
PTE.P is not set, it can lead to TF faults.

On GFX12.1, default PTE setup needs an additional bit to be

While at it, fixup the coding style too.
