89 * Note about bitfields: The u8 type is used for bitfields in ACPI tables.
90 * This is the only type that is even remotely portable. Anything else is not
91 * portable, so do not use any other bitfield types.
89 * Note: C bitfields are not used for this reason:
90 *
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.
