AFAIR, this is impossible - the kernel does NO fpu operations other
than those that are needed to save or restore FPU context at process
Hm, those are fpiemu for sure - and not fpdemu or fpeaemu?
OTOH - a tight loop of fpiemu-intensive code performs at about
78000 instructions/second, afair, so I wouldn't worry too much if
it's only 118/second.
