    sys/i386/i386        busdma_machdep.c 
  Log:
  Fix a parent tag reference count bug during tag teardown.
  
  Enable optimization for nobounce_dmamap clients by setting the map
  held by the client to NULL.  This allows the macros in bus.h to check
  against a constant to avoid function calls.
  
  Don't attempt to 'free()' contigmalloced pages in bus_dmamem_free().
  We currently leak these pages, which is not ideal, but is better than
  a panic.  The leak will be fixed when contigmalloc is merged into the
  bus dma framework after 3.0R.
