What is a user FPU vs kernel FPU in this context? By user FPU do you mean, like user FPU state in a sigframe or something? Or a kernel task's FPU? If the former I think this comment could be made more clear. Maybe just drop the bit about user FPUs. At least the comment makes more sense to me without it.
