  • Completed a major update for the acpi_get_object_info external interface.
    Changes include:
    - Support for variable, unlimited length HID, UID, and CID strings
    - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
    - Call the _SxW power methods on behalf of a device object
    - Determine if a device is a PCI root bridge
    - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
    These changes will require an update to all callers of this interface.
    See the ACPICA Programmer Reference for details.

    Also, update all invocations of acpi_get_object_info interface
