Things like iommu STE/CD entires are HW specified and currently
allocated from slab, so there may be something interesting there.

They could also possibly be converted to page allocations..

But I think we will come up with cases where maybe a kmemcache
specifically for KHO objects makes some sense. Need to get further
along.
