It's only a refactoring. NB2: Some targets (or1k) do not support acpi and CONFIG_ACPI is off for them. However, modules are reused between all architectures so CONFIG_ACPI is on. For those architectures, dummy stub function definitions help to resolve symbols. This change uses more of these and so it adds a couple of dummy stub definitions so that symbols for those can be resolved.
