For me, amd-iommu.h is architecture specific, for this kind of headers, if it is used by most of archs, it will be in "include/asm-generic". If it is used by several archs, it will be in "arch/*/include/asm/". So for me, at present, it is only used by x86, so is move to "arch/x86/ include/asm/"; if another archs want it, they can copy one. If quite a few archs (e.g. > 3 archs) need it, move it to "include/asm-generic".
