Handy similar GUI tool for windows: https://www.grc.com/inspectre.htm It might be worth pointing out the mitigations are multi-level and not just kernel-dependent - parts of user space programs, the kernel, system firmware and your compiler all need patching and some (many) systems will never get all of those individual bits.
