  42 * send_event: inject a specified event into guest
  43 * madt_cpu: fills @entry with Interrupt Controller Structure
  44 *           for CPU indexed by @uid in @apic_ids array,

  48 * Interface is designed for providing unified interface
  49 * to generic ACPI functionality that could be used without
  50 * knowledge about internals of actual device that implements
  51 * ACPI interface.
