Hi, Christoph

I think the DMA change is pretty uncontroversial.

There are still some questions about the x86 change: After digging a bit
deeper into the mm code I think Dave is correct about that we should
include the sme_me_mask in _PAGE_CHG_MASK.

I'll respin that patch and then I guess we need an ack from the x86 people.

Thanks,
Thomas
