Changes:
- Added header "core.h" for i2o_core.ko internal definitions
- More sparse fixes
- Changed display of TID's in sysfs attributes from XXX to 0xXXX
- Use the right functions for accessing I/O and normal memory
- Removed error handling of SCSI device errors and let the SCSI layer
take care of it
- Added new device / removed device handling to SCSI-OSM
- Make status access volatile
- Cleaned up activation of I2O controller
- Removed unnecessary wmb() and rmb() calls
- Use own struct i2o_io for I/O memory instead of struct i2o_dma

and 2400A workaround
Changes:
- Provide SG_IO access to BLOCK and EXECUTIVE class on Adaptec
controllers
- Use PRIVATE messages in SCSI-OSM because on some controllers normal
SCSI class commands like READ or READ CAPACITY cause errors
- Use new DMA and SG list creation function
- Added workaround to limit sectors per request for Adaptec 2400A
controllers

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

Changes:
- Fixed sysfs bug where user and parent links where added to the I2O
device itself
- Fixed bug when calculating TID for the event handler and cleaned up the
workflow of i2o_driver_dispatch()
- Fixed oops when no I2O device could be found for an event delivered to
Exec-OSM
- Fixed initialization of spinlock in Exec-OSM
- Fixed memory leak in i2o_cfg_passthru() and i2o_cfg_passthru()
- Removed MTRR support
- Added PCI ID of Promise SX6000 with firmware >= 1.20.x.x
- Turn of caching for ioremapped memory of in_queue
- Added initialization sequence for Promise controllers
- Moved definition of u8 / u16 / u32 for raidutils before first use

generic:
- split i2o_core into several files, grouped by same function
- I2O devices are now registered as devices and show up in sysfs
- the various I2O OSM's (e.g. i2o_scsi) now register in the I2O core
and also use the 2.6 driver mechanism.
- I2O messages will be created in the message frame instead of creating
it in local memory and copying it over later on.
- context list for 64 pointer to 32 context conversion now uses a
double linked list
PCI:
- driver now registers as a PCI device driver and uses probe function to
get the possible controllers. (needed for hotplugging)
- converted DMA handling from pci_* to generic dma_* functions
Block OSM:
- use one request queue per I2O block device instead of one per
controller
- I2O block devices and queues are allocated dynamically and therefore
no more limit of block devices
SCSI OSM:
- corrected bug in SCSI reply function which caused the memory to be
freed before the done function was called.
- one I2O controller registers as one scsi host instead of one scsi host
per channel
- no more ch,id,lun => tid mapping table
Config OSM:
- added ioctl32 for passthru and getiops.
- removed ioctl_html
Documentation:
- removed TODO entries from README
- moved docs under Documentation/i2o

I have made a mistake in the kernel header i2o-dev.h. All structures there
begin with the "iop" first, but in my structure the order is reversed.

* Add a pass-thru ioctl to i2o_config, which is needed to work with the
Adaptec management software.

From: Markus Lidel <Markus.Lidel@shadowconnect.com>
drivers/message/i2o/i2o_block.c:
- corrected the initialization sequence of the request queues.
- added initialization to queue spinlocks.
- release device in i2o_scan because else the device could not be queried.
- i2o_block event threads wait on signal KILL but signal TERM was sent.
drivers/message/i2o/i2o_core.c:
- set the HRT length to 0 at initialization, to avoid calling free on
unallocated memory.
- i2o_core event threads wait on signal KILL but signal TERM was sent.
- added a limit of 3 tries to get the HRT from the controller.
- removed the dpt parameter, which was used to force DPT controllers get
handled by the i2o driver. Now all available i2o controllers will be
handled by this driver.
drivers/message/i2o/i2o_scsi.c:
- beautifying of printk calls.
- added scsi_unregister to properly clean up on module unload.
drivers/message/i2o/Kconfig:
- added help for i2o_block and i2o_scsi to describe the differences between
the two drivers.
include/linux/i2o-dev.h:
- cleaned typo "tate" into "state".
include/linux/i2o.h:
- removed defines from i2o_block and insert it here.
