Fiasco.OC interrupt handling

Hi,

I'm looking into the interrupt handling in Fiasco.OC r.40 (x86/amd64).  
Browsing the code, it appears that the IDT only gets set up on CPU 0 and 
therefore on a multicore platform all interrupt handling from the 
kernel's perspective is from core 0. Of course the user-level handlers 
themselves may be elsewhere.  Do I have this correct or am I 
misunderstanding?

Thanks,
Daniel
