Ed Maste b3327f62f0 Enable KPTI by default on amd64 for non-AMD CPUs ... Kernel Page Table Isolation (KPTI) was introduced in r328083 as a mitigation for the 'Meltdown' vulnerability. AMD CPUs are not affected, per https://www.amd.com/en/corporate/speculative-execution: We believe AMD processors are not susceptible due to our use of privilege level protections within paging architecture and no mitigation is required. Thus default KPTI to off for AMD CPUs, and to on for others. This may be refined later as we obtain more specific information on the sets of CPUs that are and are not affected.
