Subject: Re: Generic IOMMU pooled allocator

Turned out that I was able to iterate over it, and remove
both the ->cookie_to_index and the ->demap indirection from
iommu_tbl_ops.
That leaves only the odd iommu_flushall() hook, I'm trying
to find the history behind that (needed for sun4u platforms,
afaik, and not sure if there are other ways to achieve this).
Just sent out a new patch-set, which should reach all the
people/lists on this thread.
If it's possible, it would also help to share any preliminary
code-samples with the iommu_table_ops you folks have in mind.
Please take a look at patchv5, and share your thoughts.
