I haven't got around to my version but just to recap, I'm not going
to plumb this into shash at all. My mb interface will be ahash only.
At the same time, I will add a new vaddr interface to the top side
of ahash so that vaddr users do not have to create an SG list
unnecessarily. The API will handle the mechanics of plumbing this
into drivers that require SG lists. Whether all vaddrs are allowed
or only a subset (kmalloc + vmalloc) is yet to be decided. Of
course it wouldn't be hard to extend (kmalloc + vmalloc) to all
addresses by simply allocating a bounce buffer + copying.
Cheers,
