This seems to be the most salient point. I was missing the fact that
this replaces custom hacks and "special" pages with an explicit "just
pass this pre-mapped address down the stack". It's functionality that
might plausibly be used outside of p2p, as long as the driver can
assert that it never needs to touch the data with the cpu before
handing it off to a dma-engine.

Yup, that's a good way to put it. If I resend this patchset, I'll
include wording like yours in the cover letter.
