AMD IOMMU: struct amd_iommu remove padding on 64 bit
Remove 16 bytes of padding from struct amd_iommu on 64bit builds reducing its size to 120 bytes, allowing it to span one fewer cachelines. Signed-off-by: Richard Kennedy <richard@rsk.demon.co.uk> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
