apic.h has defines like: #define lapic__id lapic->id Once private pages and "known virtual addr" mapping of the APICs is ready all 'lapic__XXX' will be changed to 'lapic.XXX', and the defines will be removed. Changes to smp.h for lapic_t lapic && ioapic_t ioapic pointers, currently equal to apic_base && io_apic_base, will stand alone with the private page mapping.
