It's probably a bug fix that unveils the link errors.

Thanks for the report. Error was there already, before my commits.

Mentioned commit e18a8c104d77 ("ia64: Hide the archdata.iommu field
behind generic IOMMU_API") was a fix for commit e93a1695d7fb ("iommu:
Enable compile testing for some of drivers"). After reverting both of
them (so reverting compile testing and the fix), the error is visible.

Best regards,
Krzysztof
