I have not beat on my system under UP like I have using the SMP version of the kernel, but I do know that there were windows in UP mode that this code will fix. Also, the code has been carefully scheduled to work (nearly) optimally on P5/P6 machines, so there should be a nearly unmeasurable improvement for UP even just with the swtch.s changes.
