Yes, the difference is that VT-d runs on x86 and on ia64. So there is no
single arch where the header could be placed. The amd-iommu.h file on
the other hand is x86 only and should also be moved to asm/, as I just
found out :)
And as long as PAMU is only needed on a single architecture the header
should also be arch-specific. If that changes someday the header can be
moved to a generic place.
