                         intr_machdep.h 
  Log:
  Fix isa_wrongintr.  The APIC vector was being directly assigned to a C
  function, resulting in register corruption and other nasties.  Generate
  a set of assembly functions to handle wrong-interrupt assignments.  For
  now we just EOI the apic and iret.
  
  This bug could cause an SMP box to crash on boot if a spurious IRQ #0
  interrupt occurs while it is testing for 8254 interrupt delivery.
