On ia64 with CONFIG_DMAR=n and CONFIG_SWIOTLB=y (as used in arch/ia64/configs/tiger_defconfig) there is still a link error with iommu_pass_through listed as an undefined symbol: arch/ia64/kernel/built-in.o: In function `pci_swiotlb_init': (.init.text+0x7f70): undefined reference to `iommu_pass_through' Fix it by #defining iommu_pass_through away in asm/iommu.h Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
