  19 Abstract:
  20
  21   This file contains a structure definition for the ACPI 2.0 Multiple APIC
  22   Description Table (MADT).  Any changes to the MADT table require updating the
  23   respective structure count in Madt.h and then adding the structure to the
  24   MADT defined in this file.  The table layout is defined in Madt.h and the
  25   table contents are defined in Acpi3_0.h and Madt.h.
