    kernel - Fix bug in cdev_pager_allocate() that was messing up gem/ttm
    
    * cdev_pager_allocate() was assuming that the passed vm_object handle
      was a cdev_t and populating a field in it, but that is not always the case.
      Fix the case.
    
    * This solves RBTREE corruption in drm/ttm.
