You do know that most of the sha512 asynchronous hash drivers use custom state
formats and not your new one, right?  So your code in ahash_do_req_chain() is
broken for most asynchronous hash drivers anyway.

Every driver needs to be converted by hand.  Once a driver has
been converted it'll be marked as block-only which activates
the fallback path in ahash.

Perhaps I am just slow, but could you please explain again what the
point is of all these changes?

Where is h/w accelerated ahash being used to the extent that it
justifies changing all this existing code to accommodate it?
