Split vector.s into UP and SMP specific files:
- vector.s <- stub called by i386/exception.s
- icu_vector.s <- UP
- apic_vector.s <- SMP
Split icu.s into UP and SMP specific files:
- ipl.s <- stub called by i386/exception.s (formerly icu.s)
- icu_ipl.s <- UP
- apic_ipl.s <- SMP
This was done in preparation for massive changes to the SMP INTerrupt
mechanisms. More fine tuning, such as merging ipl.s into exception.s,
may be appropriate.
