The only difference I noticed is, two files call proc_linkup rather
than proc_linkup0. The only difference between these two functions is
proc_linkup0 initialises the proc's p_threads tailq then calls
proc_linkup. As one of these is in the s3c24x0 version of initarm,
which I have hardware for, I have tested it work as expected.
