Marcel Moolenaar 27e327fdaf 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.

Based on a patch from: arun@
