Initial Performance Benchmarks of Linux's x86 Security Changes
With what is known about this bug so far, wouldn't it be possible to mitigate it by locking the kernel to one CPU core, and run user processes on the other cores?Also, if this bug lets the kernel leak data to user processes, would it also not be the case that different processes would leak data to each other?  If that is true, then it seems that just isolating the kernel wouldn't be enough.
