    kernel - Add lwkt_cpusync_quick()
    
    * Add a quick one-stage cpusync function to complement our two-stage
      interlock/deinterlock cpusync functions.
    
      The one-stage version doesn't have to spin the target cpus, only the
      originating cpu, but it can't quiesce the cpus either whereas the
      two-stage version can.
