9512fe850e98fdd448c638ca63fdd92a8a510255ahl * On IA/32, there is a single 32-bit address space that is partitioned
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * between user-level and kernel-level. copyin()/copyinstr() and
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * copyout()/copyoutstr() must check that addresses specified as
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * user-level addresses are actually at user-level. This test attempts
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * to perform an illegal copyout() to a kernel address. It asserts that
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * the fault type is DTRACEFLT_BADADDR and that the bad address is set to
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * the kernel address to which the copyout() was attempted.
