Ok, with the cross-call your "goodness()" changes are a lot more
acceptable. The thing is, that if you make goodness() quite that unwilling
to run another CPU's process, then you do need to verify some way that the
other CPU is willing to pick up the process in case it is important. Your
previous patch didn't do that.
I'll try this approach out on lmbench - I still worry about the cross-call
overhead,
