Yes, they should be helpful.  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.
