Meelis Roos db7526f925 fix integer overflow warning in i2o_block drivers/message/i2o/i2o_block.c: In function 'i2o_block_transfer': drivers/message/i2o/i2o_block.c:837: warning: integer overflow in expression msg->u.head[1] = cpu_to_le32(I2O_CMD_PRIVATE << 24 \| HOST_TID << 12 \| tid); and I2O_CMD_PRIVATE is defined as 0xFF. This gets "0xFF0100 \| tid" and fits into 32-bit unsigned but not into 32-bit signed integer properly. Target value is defined as u32 so the claculation does not fit during computation. Change local variable tid to u32 so the whole expression is of u32 type and fits well into u32 result.

CREDITS

	This work was made possible by 

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

Symbios Logic (Now LSI)
	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)
