  Log:
  Because alpha can't access memory in 16-bit granularity,
  we're using an atomic operation to clear the suspend flag
  in fxp_start().  Since other architectures may need the
  same thing, we want to do it all the time and not only
  in the __alpha__ case.  However, we don't want to use
  atomic operations on 16-bit integers, because those may
  not be available on any architecture.  We're thus faking
  a 32-bit atomic operation here.  This patch also deals
  with endianness here.
