Thanks. That is more helpful than the previous message.
I was leery of disturbing the swiotlb_* API needlessly, especially
since that involves ia64 as well. But if you think that would be
better, then I'll work in that direction.
Patches to follow...

P.S. BTW, "dumb" is a term that is both subjective and perjorative.
IMHO, it is "dumb" to use the word "dumb" in public discourse...
