Instead, add arguments to vmapbuf. Since this argument is always a pointer use a type of void * and cast to vm_offset_t in vmapbuf. (In CheriBSD we've altered vm_fault_quick_hold_pages to take a pointer and check its bounds.) In no other situtation does b_data contain a user pointer and vmapbuf replaces b_data with the actual mapping.
