update the type for num_syncobj_handles from __u32 to _u16 with
required padding.
This breaks the UAPI for big-endian platforms but this is deliberate
and harmless since userqueues is still a beta feature. It is enabled
via module parameter and need the right fw support to work.

"AMDGPU_GEM_DOMAIN_MMIO_REMAP" - Never activated as UAPI and it turned
out that this was to inflexible.
Allocate the MMIO_REMAP buffer object as a regular GEM BO and explicitly
move it into the fixed AMDGPU_PL_MMIO_REMAP placement at the TTM level.
This avoids relying on GEM domain bits for MMIO_REMAP, keeps the
placement purely internal, and makes the lifetime and pinning of the
global MMIO_REMAP BO explicit. The BO is pinned in TTM so it cannot be
migrated or evicted.
The corresponding free path relies on normal DRM teardown ordering,
where no further user ioctls can access the global BO once TTM teardown
begins.
v2 (Srini):
- Updated patch title.
- Drop use of AMDGPU_GEM_DOMAIN_MMIO_REMAP in amdgpu_ttm.c. The
MMIO_REMAP domain bit is removed from UAPI, so keep the MMIO_REMAP BO
allocation domain-less (bp.domain = 0) and rely on the TTM placement
(AMDGPU_PL_MMIO_REMAP) for backing/pinning.
- Keep fdinfo/mem-stats visibility for MMIO_REMAP by classifying BOs
based on bo->tbo.resource->mem_type == AMDGPU_PL_MMIO_REMAP, since the
domain bit is removed.
v3: Squash patches #1 & #3

In the context of the amdgpu uAPI, the PRT flag is referring only
to unmapped pages of a partially resident texture (aka. sparse
resource), but not the full resource.
Virtual addresses marked with this flag behave as follows:
- Reads return zero
- Writes are discarded

This type is used to support a 3x4 matrix in colorops. A 3x4
matrix uses the last column as a "bias" column. Some HW exposes
support for 3x4. The calculation looks like:
out matrix in
|R| |0 1 2 3 | | R |
|G| = |4 5 6 7 | x | G |
|B| |8 9 10 11| | B |
|1.0|
This is also the first colorop where we need a blob property to
program the property. For that we'll introduce a new DATA
property that can be used by all colorop TYPEs requiring a
blob. The way a DATA blob is read depends on the TYPE of
the colorop.
We only create the DATA property for property types that
need it.

The term "HQD" is CP-specific and doesn't
accurately describe the queue resources for other IP blocks like SDMA,
VCN, or VPE. This change:
1. Renames `num_hqds` to `num_slots` in amdgpu_kms.c to better reflect
the generic nature of the resource counting
2. Updates the UAPI struct member from `userq_num_hqds` to `userq_num_slots`
3. Maintains the same functionality while using more appropriate terminology

This change exposes the number of available user queue instances
for each hardware IP type (GFX, COMPUTE, SDMA) through the
drm_amdgpu_info_hw_ip interface.
Key changes:
1. Added userq_num_instance field to drm_amdgpu_info_hw_ip structure
2. Implemented counting of available HQD slots using:
- mes.gfx_hqd_mask for GFX queues
- mes.compute_hqd_mask for COMPUTE queues
- mes.sdma_hqd_mask for SDMA queues
3. Only counts available instances when user queues are enabled
(!disable_uq)
v2: using the adev->mes.gfx_hqd_mask[]/compute_hqd_mask[]/sdma_hqd_mask[] masks
to determine the number of queue slots available for each engine type (Alex)
v3: rename userq_num_instance to userq_num_hqds (Alex)

This patch adds a new subquery (AMDGPU_INFO_UQ_FW_AREAS) in
AMDGPU_INFO_IOCTL to get the size and alignment of shadow
and csa objects from the FW setup. This information is
required for the userqueue consumers.
V2: Added Alex's suggestions and addressed review comments:
- make this query IP specific (GFX/SDMA etc)
- give a better title (AMDGPU_INFO_UQ_METADATA)
- restructured the code as per sample code shared by Alex
V3: Split the UAPI patch from shadow_size_fn modifications
V4: Addressed review comments from UAPI review (Marek/Pierre-Eric)
- Change the query name to AMDGPU_INFO_UQ_FW_AREAS
- remove unused inpur parameter for AMDGPU_HW_IP*
