I already put a sledgehammer to __cpu_up with that last
patch. Some more hammering surely wouldnt be a big issue. Unlike i386
we actually still have a chance to test all relevant platforms, so I
dont think it is a big issue.
What changes did you plan?
P.S.: An alternative would be to define a new genapic subarch that
you only enable when you detect cpuhotplug support at boot.
Again just commenting on the text, not patch sorry.
