  Log:
  Introduce bus_dmamap_load_mbuf_sg().  Instead of taking a callback arg, this
  cuts to the chase and fills in a provided s/g list.  This is meant to optimize
  out the cost of the callback since the callback doesn't serve much purpose for
  mbufs since mbuf loads will never be deferred.  This is just for amd64 and
  i386 at the moment, other arches will be coming shortly.
