It then uses it on poly1305 to eliminate duplication between architectures. In particular, instead of having complete update functions for each architecture, reduce it to a block function per architecture instead. The partial block handling is handled by the generic library layer. The poly1305 implementation was anomalous due to the inability to call setkey in softirq. This has since been resolved with the addition of cloning. Add setkey to poly1305 and switch the IPsec code (rfc7539) to use that. Finally add a partial blocks conversion for polyval.
