Routine Description:

KeFlushWriteBuffer
    Flushes all write buffers and/or other data storing or reordering
    hardware on the current processor.  This ensures that all previous
    writes will occur before any new reads or writes are completed.

    In the simulation environment, there is no write buffer and nothing
    needs to be done.

Arguments:

    None

Return Value:

    None.
