    sys/cam              cam_periph.c 
  Log:
  At Justin's request, limit the size of buffers that can be mapped into
  and out of kernel address space (via the pass(4) and xpt(4) peripheral
  drivers) to 64K (DFLTPHYS).  Some controllers, like the Adaptec 1542,
  don't support more than 64K transactions.
  
  We plan on eventually having the capability of limiting this size based
  on min(MAXPHYS, controller max), but since that capability isn't here yet,
  limit things to the lowest common denominator.
