You would need to defeat the standard way of checking if in
the system so the standard system calls and interrupt code
would think user space was executing. As I recall there was
some mapping tricks played so that while not actually in the
system map, it was still available.
I had only a brief encounter with these calls so I may not
have all the details right :(
