Sorry about fallout from my dma mapping ops unification.
= From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Subject: [PATCH] IA64: fix the compile error on IA64_DIG_VTD
This moves iommu_detected to arch/ia64/kernel/dma-mapping.c from arch/ia64/kernel/pci-swiotlb.c to fix the following error on on IA64_DIG_VTD:
arch/ia64/kernel/built-in.o: In function `pci_iommu_init': pci-dma.c:(.init.text+0xa021): undefined reference to `iommu_detected' pci-dma.c:(.init.text+0xa030): undefined reference to `iommu_detected' drivers/built-in.o: In function `detect_intel_iommu': (.init.text+0x11c0): undefined reference to `iommu_detected' drivers/built-in.o: In function `detect_intel_iommu': (.init.text+0x11e1): undefined reference to `iommu_detected'
iommu_detected is used to handle IOMMUs so I guess that arch/ia64/kernel/dma-mapping.c is ok (there might be a better place for it though).
