Markus Lidel b2aaee33fb [PATCH] I2O: Adaptec specific SG_IO access, firmware access through sysfs 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

	This work was made possible by 

Red Hat Software
	Funding for the Building #3 part of the project

	Host adapters, hints, known to work platforms when I hit
	compatibility problems

STATUS:

o	The core setup works within limits.
o	The scsi layer seems to almost work. 
           I'm still chasing down the hang bug.
o	The block OSM is mostly functional
o	LAN OSM works with FDDI and Ethernet cards.

TO DO:

General:
o	Provide hidden address space if asked
o	Long term message flow control
o	PCI IOP's without interrupts are not supported yet
o	Push FAIL handling into the core
o	DDM control interfaces for module load etc
o       Add I2O 2.0 support (Deffered to 2.5 kernel)

Block:
o	Multiple major numbers
o	Read ahead and cache handling stuff. Talk to Ingo and people
o	Power management
o	Finish Media changers

SCSI:
o	Find the right way to associate drives/luns/busses

Lan:	
o	Performance tuning
o	Test Fibre Channel code

Tape:
o	Anyone seen anything implementing this ?
           (D.S: Will attempt to do so if spare cycles permit)
