/**

*
* The APIC consists of one (or more) IO-APIC and one LAPIC (Local APIC)
* for each core. Currently we only support the, by far, most popular and
* prevalent setup with a single IO-APIC.
*
* Please Call apic_init() once, providing an acpi_information structure,
* before using the other functions.
