Summary: "While the Kernel Page Table Isolation (KPTI) patches were

quick to land in the mainline Linux kernel for addressing the Meltdown

CPU vulnerability, the "Retpoline" patches are still being worked on as

the leading approach on the Linux side for dealing with the Spectre CPU

vulnerability. The Retpoline patches are said to have little impact on

performance, but here are our benchmarks of these kernel patches for

seeing how they affect a variety of AMD and Intel systems."
