Modify the GTDT table parsing logic to prevent reading past the ACPI buffer lengths provided and to make it consistent with other table parsers. This includes converting the do-while loop in ParseAcpiGtdt() into a while loop. Remove a check which ensures that the entire Platform GT Block Structure buffer has been parsed. The ACPI specification does not ban from defining buffers which are larger than the size indicated by the count and sizes of substructures which constitute it. Change the data type of the Length parameter to the DumpGTBlock() function to reflect the width of the respective ACPI structure's field.
