  Log:
  Don't panic for delivery of a multiplexed SWI.  Most SWI handlers
  don't take an arg, but swi_generic() is special in order to avoid one
  whole conditional branch in the old SWI dispatch code.  The new SWI
  dispatch code passed it a garbage arg.  Bypass swi_generic() and call
  swi_dispatcher() directly, like the corresponding alpha code has always
  done.
  
  The panic was rare because because it only occurred if more than one
  of the {sio,cy,rc} drivers was configured and one was active, and the
  cy driver doesn't even compile.
