+ * This utility function creates and maps an instance of empty slot,
+ * which is a dummy device which simply read as zero, and ignore writes.
+ * An empty slot sit on a bus, and no bus errors are generated when it is
+ * accessed.
+ * Guest accesses can be traced, using the '-trace empty_slot\*' command
+ * line argument.
+ * The device is mapped at priority -10000, which means that you can
+ * use it to cover a large region and then map other devices on top of it
+ * if necessary.
