  Do not pre-map the I/O port space. On the Intel Tiger 4 this conflicts
  with a memory mapped I/O range that's immediately before it and is
  not 256MB aligned. As a result, when an address is accessed in the
  memory mapped range and a direct mapping is added for it, it overlaps
  with the pre-mapped I/O port space and causes a machine check.
