  Modified files:
    sys/i386/isa         apic_vector.s intr_machdep.c 
  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.
