    Changes:
     - Added Bus-OSM which could be used by user space programs to reset a
       channel on the controller
     - Make ioctl's in Config-OSM obsolete in prefer for sysfs attributes and
       move those to its own file
     - Added sysfs attribute for firmware read and write access for I2O
       controllers
     - Added special handling of firmware read and write access for Adaptec
       controllers
     - Added vendor id and product id as sysfs-attribute to Executive classes
     - Added automatic notification of LCT change handling to Exec-OSM
     - Added flushing function to Block-OSM for later barrier implementation
     - Use PRIVATE messages for Block access on Adaptec controllers, which are
       faster then BLOCK class access
     - Cleaned up support for Promise controller
     - New messages are now detected using the IRQ status register as
       suggested by the I2O spec
     - Added i2o_dma_high() and i2o_dma_low() functions
     - Added facility for SG tablesize calculation when using 32-bit and
       64-bit DMA addresses
     - Added i2o_dma_map_single() and i2o_dma_map_sg() which could build the
       SG list for 32-bit as well as 64-bit DMA addresses
