Btw, you already agreed with a generic iommu= parameter for lazy IO/TLB

Hmm, now is better than the future? I think that now you can add
something like 'disable_batching_flush' as a common parameter and
change AMD IOMMU to use it.
in http://lkml.org/lkml/2008/9/17/376
And since we already have a iommu=fullflush parameter it makes sense of
make it generic.
