This series implements VM_BIND decompression support in the XE driver
for both non-fault mode and fault mode.

Tested with https://patchwork.freedesktop.org/series/154711/
which validates basic VM_BIND DECOMPRESS behavior for both
regular and FAULT_MODE VMs.

v3: (Matt)
   - s/xe_bo_schedule_decompress/xe_bo_decompress
   - skip the decrompress step if the BO isn't in VRAM
   - start/size not required in xe_bo_schedule_decompress
   - Use xe_bo_move_notify instead of xe_vm_invalidate_vma
     with respect to invalidation.
   - Nits
 
v2:
   - Add kernel doc (Matt)
   - Move decompression work out of vm_bind ioctl. (Matt)
   - Put that work in a small helper at the BO/migrate layer invoke it
     from vma_lock_and_validate which already runs under drm_exec.
   - Move lightweight checks to vm_bind_ioctl_check_args (Matthew Auld)


Nitin Gote (3):
  drm/xe: add VM_BIND DECOMPRESS uapi flag
  drm/xe: add xe_migrate_resolve wrapper and is_vram_resolve support
  drm/xe: implement VM_BIND decompression in vm_bind_ioctl
