[ACPI] ACPICA 20051102
Modified the subsystem initialization sequence to improve GPE support. The GPE initialization has been split into two parts in order to defer execution of the _PRW methods (Power Resources for Wake) until after the hardware is fully initialized and the SCI handler is installed. This allows the _PRW methods to access fields protected by the Global Lock. This will fix systems where a NO_GLOBAL_LOCK exception has been seen during initialization. Fixed a regression with the ConcatenateResTemplate() ASL operator introduced in the 20051021 release. Implemented support for "local" internal ACPI object types within the debugger "Object" command and the acpi_walk_namespace() external interfaces. These local types include RegionFields, BankFields, IndexFields, Alias, and reference objects. Moved common AML resource handling code into a new file, "utresrc.c". This code is shared by both the Resource Manager and the AML Debugger. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
