  Modified files:
    sys/dev/aac          aac.c aac_pci.c aacvar.h 
  Log:
  Take the plunge and make this driver be INTR_FAST.  This re-arranges the
  interrupt handler so that no locks are needed, and schedules the
  command completion routine with a taskqueue_fast.  This also corrects the
  locking in the command thread and removes the need for operation flags.
  
  Simple load tests show that this is now considerably faster than FreeBSD 4.x
  in the SMP case when multiple i/o tasks are running.
