I still got one message (grmbl is a dual Pentium II SMP machine):

# fgrep non-running /var/log/messages
Jan 29 11:50:31 grmbl kernel: handle_mm_fault called by non-running (1) task from c01113ee!

Obviously the call takes place in do_page_fault

# fgrep c0111 /boot/System.map
c0111004 t set_pte_phys
c011104c T set_fixmap
c0111080 T free_initmem
