FWIW the crypto API has always been supposed to handle SG entries
that cross page boundaries. There were a couple of bugs in this
area but AFAIK they've all been fixed.
Of course I cannot guarantee that every crypto driver also handles
it correctly, but at least we have a few test vectors which test
the page-crossing case specifically.
