That certainly would be a nice twist. Suddenly all of those old chips out there run faster than the fancy new whiz-bangs just because they don't need the super-secure kernel shuffling :-)
Now I wonder if single core CPUs are affected.
This issue is related to paralelization optimizations. Thus I wonder whether a machine that doesn't paralelize is affected.
It's the pipeline that's affected. That's part of a single-core cpu, so yes it probably is affected.
I also wonder if a virtual machine that is given a single core of a multi-core CPU is affected.
I wonder what virtualisation does full stop. Obviously, if there are multiple virtual systems it can't control what other systems are running when, but if it gives away things like passwords etc then there's a problem.
