+ * This table is used to convert an input UUID ascii string to a 16 byte

+ * the index within the 36-byte UUID string where the associated 2-byte
+ * hex value can be found.
+ *
+ * 36-byte UUID strings are of the form:
+ *     aabbccdd-eeff-gghh-iijj-kkllmmnnoopp
+ * Where aa-pp are one byte hex numbers, made up of two hex digits
+ *
+ * Note: This table is basically the inverse of the string-to-offset table
+ * found in the ACPI spec in the description of the to_UUID macro.
