  Modified files:
    sys/amd64/amd64      apic_vector.S 
    sys/i386/i386        apic_vector.s 
  Log:
  Use xchg in Xcpustop to close a race and make cpustop_restartfunc truly
  one-shot in the SMP case (before using the simple mov / cmp / mov sequence
  could allow multiple CPUs to execute the restart function on resume).
