    drm/xe/xe_vm: Implement xe_vm_get_property_ioctl
    
    Add support for userspace to request a list of observed faults
    from a specified VM.
    
    v2:
    - Only allow querying of failed pagefaults (Matt Brost)
    
    v3:
    - Remove unnecessary size parameter from helper function, as it
      is a property of the arguments. (jcavitt)
    - Remove unnecessary copy_from_user (Jainxun)
    - Set address_precision to 1 (Jainxun)
    - Report max size instead of dynamic size for memory allocation
      purposes.  Total memory usage is reported separately.
    
    v4:
    - Return int from xe_vm_get_property_size (Shuicheng)
    - Fix memory leak (Shuicheng)
    - Remove unnecessary size variable (jcavitt)
    
    v5:
    - Rename ioctl to xe_vm_get_faults_ioctl (jcavitt)
    - Update fill_property_pfs to eliminate need for kzalloc (Jianxun)
    
    v6:
    - Repair and move fill_faults break condition (Dan Carpenter)
    - Free vm after use (jcavitt)
    - Combine assertions (jcavitt)
    - Expand size check in xe_vm_get_faults_ioctl (jcavitt)
    - Remove return mask from fill_faults, as return is already -EFAULT or 0
      (jcavitt)
    
    v7:
    - Revert back to using xe_vm_get_property_ioctl
    - Apply better copy_to_user logic (jcavitt)
    
    v8:
    - Fix and clean up error value handling in ioctl (jcavitt)
    - Reapply return mask for fill_faults (jcavitt)
    
    v9:
    - Future-proof size logic for zero-size properties (jcavitt)
    - Add access and fault types (Jianxun)
    - Remove address type (Jianxun)
    
    v10:
    - Remove unnecessary switch case logic (Raag)
    - Compress size get, size validation, and property fill functions into a
      single helper function (jcavitt)
    - Assert valid size (jcavitt)
    
    v11:
    - Remove unnecessary else condition
    - Correct backwards helper function size logic (jcavitt)
    
    v12:
    - Use size_t instead of int (Raag)
    
    v13:
    - Remove engine class and instance (Ivan)
