Hi all,
  I've a question. how would a cpu know from an IPI, if it's on a trap handler 
underneath. Looking at entry.S, I see that trap handlers push entry vector on 
stack, so I suppose one could walk down the frames (there's prob a better 
way). Moreover, what if the IPI comes right before the entry vector is pushed? 
Does x86 disable upon trap?

Thanks for any help,
Mukesh
