There is no way to recover that in efficiency, at
least not for a long time.
So don't enable SMP on a single cpu system. Easy enough to avoid.
Why would anyone want to enable SMP on a single CPU system anyway.
Actually, I believe all the new boot disks / ISOs are all SMP-enabled, so
unless you build a custom kernel (some ppl do just run GENERIC ... I'm not
one, mind you), you could be running an SMP-enabled kernel on a UP system
without even knowing it ...
