I must be missing something, I think.  What's particularly optimal about the
code in hash_sendpage() but not hash_sendmsg()?  Is it that the former uses
finup/digest, but the latter ony does update+final?

A lot of hardware hashes can't perform partial updates, so they
will always fall back to software unless you use finup/digest.
