Kroah-Hartman: Meltdown and Spectre Linux Kernel Status - Update

Here's abrief update from Greg Kroah-Hartman on the kernel's handling of theMeltdown and Spectre vulnerabilities. "This shows that my kernel isproperly mitigating the Meltdown problem by implementing PTI (Page TableIsolation), and that my system is still vulnerable to the Spectre variant1, but is trying really hard to resolve the variant 2, but is not quitethere (because I did not build my kernel with a compiler to properlysupport the retpoline feature)."
