v3 modifies the block helper so that arrays can be used as state. This is based on https://patchwork.kernel.org/project/linux-crypto/list/?series=955753 https://patchwork.kernel.org/project/linux-crypto/list/?series=957401 This series introduces a partial block helper for lib/crypto hash algorithms based on the one from sha256_base. 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. It also has just a single user, which is chacha20poly1305 that is hard-coded to use poly1305. Replace the gratuitous use of ahash in chacha20poly1305 with the lib/crypto poly1305 instead. This then allows the shash poly1305 to be removed.
