This patch provides emulation for all FPU instructions except fsave/frstore &

While the main purpose of the patch is to avoid current and future "gotchas"
on FPU intructions used by various OS boot-loaders, it is complete enough to
run DOS realmode FPU applications and benchmarks, but don't expect to set any
speed records.
What happens when one of these in hypervisor FPU instructions raise
an exception?
That's accounted for and plumbed correctly.
