amd_iommu: fix nasty bug that caused ILLEGAL_DEVICE_TABLE_ENTRY errors
We are on 64-bit so better use u64 instead of u32 to deal with addresses: static void __init iommu_set_device_table(struct amd_iommu *iommu) { u64 entry; ... entry = virt_to_phys(amd_iommu_dev_table); ... (I am wondering why gcc 4.2.x did not warn about the assignment between u32 and unsigned long.)
