- Add new funcions for device state stuff; acpi_get_current_device_state() and acpi_set_device_state() - Add new funcions for power resource stuff; acpi_powerres_init(), acpi_powerres_debug(), acpi_get_current_powerres_state() and acpi_set_powerres_state() These were implemented based on 7.1, 7.2, 7.2.2, 7.2.3, 7.2.4, 7.3, 7.3.3, 7.4, 7.4.1, 7.4.2, 7.4.3 and 7.5 of ACPI spec 1.0b.
