    Subject[PATCH] Mark i2o config broken on 64-bit platforms.
    Mark i2o config broken on 64-bit platforms as it generates these:

    In file included from drivers/message/i2o/config-osm.c:39:
    drivers/message/i2o/i2o_config.c: In function 'i2o_cfg_passthru':
    drivers/message/i2o/i2o_config.c:889: warning: cast to pointer from integer of different size
    drivers/message/i2o/i2o_config.c:945: warning: cast to pointer from integer of different size

    which are apparently non-trivial to fix (eg: inserting a cast through unsigned
    long is not correct according to Linus). This would be due to struct
    sg_simple_element only having a 32-bit addr_bus value.

    There are also a number of "TODO 64bit fix" comments.
