For this sake we define IO_APIC_SLOT_SIZE constant which should cover all IO-APIC direct accessible registers. An example of a such configuration is there http://marc.info/?l=linux-kernel&m=118114792006520 | | Quoting the message | | IOAPIC[0]: apic_id 2, version 32, address 0xfec00000, GSI 0-23 | IOAPIC[1]: apic_id 3, version 32, address 0xfec80000, GSI 24-47 | IOAPIC[2]: apic_id 4, version 32, address 0xfec80400, GSI 48-71 | IOAPIC[3]: apic_id 5, version 32, address 0xfec84000, GSI 72-95 | IOAPIC[4]: apic_id 8, version 32, address 0xfec84400, GSI 96-119 | Reported-by: "Maciej W.
