Patches 1-6 applied to iommu-2.6.git. Please test. Thanks.

Please note for future reference that 'From:' lines such as the one in
your patch 1/7 should be *first* in the body of your email. The git-am
tool doesn't find them and set the authorship if you put them with the
Signed-off-bys. Also please avoid putting whitespace at the beginning of
every line of your commit comments.

I still hate patch 7, but the point was that I wouldn't have to care
about it. Once your patches 1-6 are included in known stable releases
that your SCU can recognise, it can just pass 'iommu=pt' for those.

It's only the "probably buggy" kernels with older release numbers that
you'll pass 'forcedac,pt64' to, so your mission is to get patch 7 or
some variant of it accepted into *those* kernels.
