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.
Jump prediction in the pipeline is not related to the number of cores.
I also wonder if a virtual machine that is given a single core of a multi-core CPU is affected.
