Build fixes:
- Add some missing I/O functions for non-i386 and amd64 platforms. - Stub ioremap() to NULL using a macro to ensure non-existing memory attributes are not referred when they do not exist. - Add more header files to linux/list.h to resolve driver compilation issues on Sparc64 and PowerPC platforms.
