Instead of copying current_set[cpu] to secondary_ti, directly index into
current_set by the cpu number like head_64.S.  In addition to removing
the variable, a slow to respond cpu will not clobber another cpus
stack.
Except that we don't know our CPU number at this stage do we ? IE. r24
is our HW number, is it guaranteed to be what we want to index
current_set ?
