What is the difference between Meltdown and Meltdown Prime?

1. What is the potential overhead if we disable out-of-order execution in an attempt to address the Spectre exploit?

2. In a 32-bit RISC architecture with 5-bit instruction opcode, what is the probability of activating a software-induced hardware Trojan with a trigger condition of 5 ADD instructions in a row?

3. Explain how ECC can sometimes deal with Rowhammer attack.
