Tomas Hruby e6ebac015d APIC mode uses IO APICs
- kernel turns on IO APICs if no_apic is _not_ set or is equal 0

- pci driver must use the acpi driver to setup IRQ routing otherwise
  the system cannot work correctly except systems like KVM that use
  only legacy (E)ISA IRQs 0-15

Tomas Hruby 45badf4c05 ACPI in kernel
- the ability for kernel to use ACPI tables to detect IO APICs. It is
  the bare minimum the kernel needs to know about ACPI tables.

- it will be used to find out about processors as the MPS tables are
  deprecated by ACPI and not all vendorsprovide them.
