Hi,

here is a patch-set to remove the usage of dev->archdata.iommu from
the IOMMU code in the kernel and replace its uses by the iommu per-device
private data field. The changes also remove the field entirely from
the architectures which no longer need it.

On PowerPC the field is called dev->archdata.iommu_domain and was only
used by the PAMU IOMMU driver. It gets removed as well.

The patches have been runtime tested on Intel VT-d and compile tested
with allyesconfig for:

* x86 (32 and 64 bit)
* arm and arm64
* ia64 (only drivers/ because build failed for me in
        arch/ia64)
* PPC64

Besides that the changes also survived my IOMMU tree compile tests.

Please review.

Regards,

Joerg
