The I2O layer deals with a technology that to say the least didn't catch on
in the market.
The only relevant products are some of the AMI MegaRAID - which supported I2O
and its native mode (The native mode is faster and runs on Linux), an
obscure crypto ethernet card that's now so many years out of date nobody
would use it, the old DPT controllers, which speak their own dialect and
have their own driver - and ermm.. thats about it.
We also know the code isn't in good shape as recently a patch was proposed
and queried as buggy, which in turn showed the existing code was broken
already by prior "clean up" and nobody had noticed that either.
It's coding style robot code nothing more. Like some forgotten corridor
cleaned relentlessly by a lost Roomba but where no user has trodden in years.
Move it to staging and then to /dev/null.
The headers remain as they are shared with dpt_i2o.

Changed the I2O API to create I2O messages first in kernel memory and then
transfer it at once over the PCI bus instead of sending each quad-word over
the PCI bus.

This patch updates all the device attribute callbacks that weren't
updated with the new parameter, I guess because they weren't in Greg's
tree (including drivers/pcmcia/ds.c). Without the patch these
callbacks are probably broken (and generate a warning along the lines
of "assignment from incompatible pointer type").
Please see http://lkml.org/lkml/2005/5/19/40 for the scripts I used to
update the attributes automatically.

and 64-bit DMA support
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
