  35 * ospm_status: returns status of ACPI device objects, reported

  37 * send_event: inject a specified event into guest
  38 * madt_cpu: fills @entry with Interrupt Controller Structure
  39 *           for CPU indexed by @uid in @apic_ids array,
  40 *           returned structure types are:
  41 *           0 - Local APIC, 9 - Local x2APIC, 0xB - GICC
  42 *
  43 * Interface is designed for providing unified interface
  44 * to generic ACPI functionality that could be used without
  45 * knowledge about internals of actual device that implements
  46 * ACPI interface.
