Define a psp common function: psp_get_fw_type().
Hide the GFX_FW_TYPE Changes in each ip's psp->funcs_get_fw_type callback.
(like psp_v15_0_8_get_fw_type()).

Change gmc macro AMDGPU_GMC_HOLE_START/END/MASK to 57bit if vm root
level is PDB3 for 5-level page tables.
The macro access adev without passing adev as parameter is to minimize
the code change to support 57bit, then we have to add adev variable in
several places to use the macro.
Because adev definition is not available in all amdgpu c files which
include amdgpu_gmc.h, change inline function amdgpu_gmc_sign_extend to
macro.

Add the drm_gem_huge_mnt_create() and drm_gem_get_huge_mnt() helpers
to avoid code duplication in the i915, V3D, Panfrost and Panthor
drivers. The former creates and mounts a dedicated huge tmpfs
mountpoint, for the lifetime of a DRM device, used at GEM object
initialization. The latter retrieves the dedicated huge tmpfs
mountpoint used by a DRM device.
The next commits will port drivers to these helpers.
v3:
- store huge tmpfs mountpoint in drm_device
v4:
- return 0 in builds with CONFIG_TRANSPARENT_HUGEPAGE=n
- return 0 when huge_mnt already exists
- use new vfs_parse_fs_string() helper
v5:
- remove warning on !dev->huge_mnt and reset to NULL on free
- inline drm_gem_huge_mnt_create() to remove func from text and avoid

- compile out drm_device's huge_mnt field in builds with
CONFIG_TRANSPARENT_HUGEPAGE=n
- add drm_gem_has_huge_mnt() helper
v6:
- move huge_mnt doc into ifdef'd section
- either inline or export drm_gem_huge_mnt_create()

mmap() calls on the DRM file pointer currently always end up using
mm_get_unmapped_area() to get a free mapping region. On builds with
CONFIG_TRANSPARENT_HUGEPAGE enabled, this isn't ideal for GEM objects
backed by shmem buffers on mountpoints setting the 'huge=' option
because it can't correctly figure out the potentially huge address
alignment required.
This commit introduces the drm_gem_get_unmapped_area() function which
is meant to be used as a get_unmapped_area file operation on the DRM
file pointer to lookup GEM objects based on their fake offsets and get
a properly aligned region by calling shmem_get_unmapped_area() with
the right file pointer. If a GEM object isn't available at the given
offset or if the caller isn't granted access to it, the function falls
back to mm_get_unmapped_area().
This also makes drm_gem_get_unmapped_area() part of the default GEM
file operations so that all the DRM drivers can benefit from more
efficient mappings thanks to the huge page fault handler introduced in
previous commit 'drm/shmem-helper: Add huge page fault handler'.
The shmem_get_unmapped_area() function needs to be exported so that
it can be used from the DRM subsystem.
v3:
- include <linux/sched/mm.h> in drm_gem.c
- forward to shmem layer in builds with CONFIG_TRANSPARENT_HUGEPAGE=n
v6:
- use GPL variant to export drm_gem_get_unmapped_area()
- don't export shmem_get_unmapped_area() anymore (use f_op instead)
v11:
- rename drm_gem_object_lookup_from_offset() to
drm_gem_object_lookup_at_offset()

Attempt a PMD sized PFN insertion into the VMA if the faulty address
of the fault handler is part of a huge page.
On builds with CONFIG_TRANSPARENT_HUGEPAGE enabled, if the mmap() user
address is PMD size aligned, if the GEM object is backed by shmem
buffers on mountpoints setting the 'huge=' option and if the shmem
backing store manages to allocate a huge folio, CPU mapping would then
benefit from significantly increased memcpy() performance. When these
conditions are met on a system with 2 MiB huge pages, an aligned copy
of 2 MiB would raise a single page fault instead of 4096.
v4:
- implement map_pages instead of huge_fault
v6:
- get rid of map_pages handler for now (keep it for another series
along with arm64 contpte support)
v11:
- remove page fault validity check helper
- rename drm_gem_shmem_map_pmd() to drm_gem_shmem_try_map_pmd()

For a fault at address addr, the page offset is
page_offset = (vmf->address - vma->vm_start) >> PAGE_SHIFT
= ((addr & PAGE_MASK) - vma->vm_start) >> PAGE_SHIFT
= (addr - vma->vm_start) >> PAGE_SHIFT
Since the faulty logical page offset based on VMA is
vmf->pgoff = vma->vm_pgoff + ((addr - vma->vm_start) >> PAGE_SHIFT)
We can slightly simplify the calculation using
page_offset = vmf->pgoff - vma->vm_pgoff

As a preparation for MST Panel Replay we need to move Panel Replay sink
related data into intel_connector. Move sink support booleans as well
into intel_connector. Generally this is more correct place for this data so
move PSR versions as well.
Still sink_support and sink_panel_replay_support are kept to keep CAN_PSR
and CAN_PANEL_REPLAY macros. Plan is to keep them that way as they are
widely used from patch where connector is not available.
Later we might want to clear intel_dp->psr.sink_panel_replay_support if any
of the devices in branch is not supporting Panel Replay (mst).
