You're aware that this is meant to be improved rather sooner than
later. At that point I'm then not sure a suitable LAPIC_ID() macro
could be created, as the potential users of this may not have
available all necessary inputs. I'd strongly suggest finding a way
to dynamically insert the APIC IDs (as found while booting) into
the ACPI tables. That's pretty likely how real BIOSes have to do
it too.
