Meltdown and Spectre Mitigation

Meltdown allows attackers to read arbitrary physical memory (including kernel memory) for an unprivileged user process. Meltdown uses out of order instruction execution to leak data via a processor covert channel.

Spectre abuses branch prediction and speculative execution of leak data from via a processor covert channel. Spectre can only read memory from the current process, not the kernel or other physical memory
