    sys/alpha/alpha      busdma_machdep.c 
    sys/i386/i386        busdma_machdep.c 
  Log:
  Teach bus_dmamem_free() about contigfree(). This is a bit of a hack,
  but it's better than the buggy behavior we have now. If we contigmalloc()
  buffers in bus_dmamem_alloc(), then we must configfree() them in
  bus_dmamem_free(). Trying to free() them is wrong, and will cause
  a panic (at least, it does on the alpha.)
  
  I tripped over this when trying to kldunload my busdma-ified if_rl
  driver.
