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