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