- use the unique value to save the per-cpu globalp struct like the
comment says
- don't lower the ipl to ALPHA_PSL_IPL_HIGH: we may have a pending machine
check to take and we're not prepared for that yet, as we haven't setup
our interrupt entry points. (this may only happen on sable/lynx)
- indicate the fact that the working version of smp_init_secondary() doesn't
return (this is tied up in other changes and hasn't yet been committed).
