I can do that. Do you have some background on this request for me?
Is it policy that you only want to gave SMP-kernels?
(Actually I had a similiar idea to use kernel alternatives on parisc too
to avoid different UP/SMP kernels).

Yes, it might be a little bit slower since the jumps now have one
CPU instruction more. But there is no other way to solve it unless
we drop some unneccessary kernel options for parisc.
