  Log:
  Add the ACPI MADT table APIC enumerator.  This code uses the ACPI Multiple
  APIC Descriptor Table to enumerate both I/O APICs and local APICs.  ACPI
  does not embed PCI interrupt routing information in the MADT like the MP
  Table does.  Instead, ACPI stores the PCI interrupt routing information
  in the _PRT object under each PCI bus device.  The MADT table simply
  provides hints about which interrupt vectors map to which I/O APICs.  Thus
  when using ACPI, the existing ACPI PCI bridge drivers are sufficient to
  route PCI interrupts.
