Enabling the EFI runtime *Time functions just because they're available isn't good enough. We need to know why this patch improves things, what use case does it solve? The general attitude has been that we want to invoke the runtime services less, not more, due to the huge variety of runtime implementation bugs. -- Matt Fleming, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
