Subject[patch] 4GB I/O, cut 5


- merge 2.4.6-pre1 zone changes for zone-dma32-6
- correct qlogicfc can_dma_32 flag (Arjan van de Ven)

Arjan also reported that the kernel doesn't boot on a machine with 8GB
of RAM, I'm suspecting the zone-dma32-6 changes. If someone has access
to such a machine, please try it.

There are no bug fixes in this release either - apart from the above
problem, no known bugs exists. I'll be donating a virtual beer for the
first spotted bug.

The patch can be considered stable, it's received quite a bit of testing
on highend hardware. Here's a plug from one such tester:

"Regarding performance of this patch, it is providing us with the highest
aggregate throughput for reads of any of the recent kernels for multiple
IOs - up to 185MB/s continuous through both controllers :)"
