83 * All tables must be byte-packed to match the ACPI specification, since
84 * the tables are provided by the system BIOS.
89 * Note: C bitfields are not used for this reason:
91 * "Bitfields are great and easy to read, but unfortunately the C language
92 * does not specify the layout of bitfields in memory, which means they are
93 * essentially useless for dealing with packed data in on-disk formats or
94 * binary wire protocols." (Or ACPI tables and buffers.) "If you ask me,
95 * this decision was a design error in C. Ritchie could have picked an order
96 * and stuck with it." Norman Ramsey.
