@lx It's probably gonna be some time until we see fixes. Spectre's apparently hard to exploit, but also hard to fix:
See http://kroah.com/log/blog/2018/01/06/meltdown-status/
TLDR: Numerous patches on the mailing lists, some don't even build, kernel devs worked on #Meltdown first, had no real info in #Spectre, no upstream fixes yet
