[ACPI] ACPICA 20051102

Browse Source 
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.
