Change 29176 by marcel at marcel_nfs on 2003/04/17 21:26:35

	Manually set psr.cpl to 3 (=user) when constructing the
	syscall frame. This allows us to check these bits to
	determine whether we're going to return to user space or
	not. Note that the mov-to-psr ignores psr.cpl and the
	mov-from-psr zeroes it.
