ACPICA: Fix to allow region arguments to reference other scopes
Allow referenced objects to be in a different scope. http://www.acpica.org/bugzilla/show_bug.cgi?id=937 http://marc.info/?l=linux-acpi&m=131636632718222&w=2 ACPI Error: [RAMB] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359) ACPI Exception: AE_NOT_FOUND, Could not execute arguments for [RAMW] (Region) (20110112/nsinit-349) Scope (_SB) { Name (RAMB, 0xDF5A1018) OperationRegion (\RAMW, SystemMemory, RAMB, 0x00010000) } For above ASL code, we need to save scope node(\_SB) to lookup the argument node(\_SB.RAMB).
