SVN rev 190569 on 2009-03-30 18:47:13Z by jhb
MFC: Use a DMA boundary of 4GB to prevent individual transactions from
crossing a 4GB address boundary. Due to bus_size_t type limitations, the
driver uses a 2GB boundary in PAE kernels. This fixes a data corruption
issue when using twa(4) in machines with >= 8 GB of RAM.
