 Why do you sepcial case cpu 0 here?
 
 Isn't the problem that you disable cpus where interrupts are routed to
 (w/o rerouting those interrupts)?
 
 This nowdadys is not the same as disabling interrupts on cpu 0 (and also
 is a machine dependent thing).
 
 We could either add some (more or lesss automatic) rewiring of interrupts
 code to cpuctl - or (much simpler) write this off as pilot error.
