- 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.
