  Log:
  Do the first and mostly mechanical step of adding mutex support to the
  bus_dma async callback scheme.  Note that sparc64 does not seem to do
  async callbacks.  Note that ia64 callbacks might not be MPSAFE at the
  moment.  Note that powerpc doesn't seem to do async callbacks due to
  the implementation being incomplete.
