ACPI: Support Generic Initiator only domains
Generic Initiators are a new ACPI concept that allows for the description of proximity domains that contain a device which performs memory access (such as a network card) but neither host CPU nor Memory. This patch has the parsing code and provides the infrastructure for an architecture to associate these new domains with their nearest memory processing node.
