PCI: iomem bigger than 4GB

PCI: iomem bigger than 4GB

[Ashish Singhai]

Hello,

Please refer to Andrew' post on this thread on PCI
subsystem assigning prefetchable memory bigger than
4GB:

http://lkml.org/lkml/2006/11/24/160

This patch is not included in 2.6.20.1 or earlier --
it would be helpful if we could have this patch
considered. I have tried it in a simulated environment
and it works.

Thanks.

Ashish

PS: Pls. CC: me on any replies since I am not
subscribed to LKML.

If a devices advertises a prefetchable BAR bigger than
4GB then the address space is not correctly assigned.
