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

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