* operand is a memory operand: ADD, ADC, AND, BTC, BTR, BTS, CMPXCHG,
* CMPXCH8B, DEC, INC, NEG, NOT, OR, SBB, SUB, XOR, XADD, and XCHG. If
* the LOCK prefix is used with one of these instructions and the source
* operand is a memory operand, an undefined opcode exception (#UD) will
* be generated. An undefined opcode exception will also be generated if
* the LOCK prefix is used with any instruction not in the above list.
* The XCHG instruction always asserts the LOCK# signal regardless of the
* presence or absence of the LOCK prefix.
