Hi Joerg,
Thanks for fix up this issue!
I forgot to test the changes against IA64 platform. There's another
issue related to IA64, I will send out the patch soon. I have setup
cross compilation environment for IA64 and verified all changes
passing compilation tests.
Thanks!
Gerry

in function iommu_support_dev_iotlb(),return value of device_to_iommu()
is used without checking, this could cause NULL pointer issue.

This is a issue, our BIOS also supports several ATSR which have the same
segment.
Good fix :)

"index" needs to be signed for the error handling to work. I deleted a
little bit of obsolete cruft related to "index" and "start_index" as
well.
