  Modified files:
    sys/alpha/include    bus.h 
    sys/ia64/include     bus.h 
    sys/i386/include     bus_at386.h bus_pc98.h 
  Log:
  Axe the barrier_{read,write,rw}() helper functions as this method of
  doing memory barriers doesn't really scale well for the ia64.  Also,
  memory barriers are more a property of the CPU than bus space.
