  SVN rev 217360 on 2011-01-13 17:00:22Z by jhb
  
  If an interrupt on an I/O APIC is moved to a different CPU after it has
  started to execute, it seems that the corresponding ISR bit in the "old"
  local APIC can be cleared.  This causes the local APIC interrupt routine
  to fail to find an interrupt to service.  Rather than panic'ing in this
  case, simply return from the interrupt without sending an EOI to the
  local APIC.  If there are any other pending interrupts in other ISR
  registers, the local APIC will assert a new interrupt.
