Awesome, thanks for doing this! I was just planning to do "blkcipher" for now, but your patches will take care of almost all of "ablkcipher" too. A few things I noticed from quickly skimming through your patches: "ecb-des3-omap", "cbc-des3-omap", "atmel-ecb-tdes", "atmel-cbc-tdes", and "atmel-ofb-tdes" had their min and/or max key size incorrectly changed to 8 (DES_BLOCK_SIZE or DES3_EDE_BLOCK_SIZE) rather than left as 24 (DES3_EDE_KEY_SIZE or 3*DES_KEY_SIZE). cra_blocksize for "atmel-cfb64-aes" was changed from CFB64_BLOCK_SIZE to AES_BLOCKSIZE. Intentional? cra_blocksize for "stm32-ctr-aes" and for "cfb-aes-mtk" was changed from 1 to AES_BLOCK_SIZE. Intentional? CRYPTO_ALG_NEED_FALLBACK was added to "cbc-des-picoxcell" and "ecb-des-picoxcell". Intentional? In drivers/crypto/ixp4xx_crypto.c, .walksize was set on "rfc3686(ctr(aes))" rather than .chunksize. Intentional? In drivers/crypto/qce/, CRYPTO_ALG_TYPE_ABLKCIPHER should be replaced with CRYPTO_ALG_TYPE_SKCIPHER. In drivers/crypto/stm32/, could rename crypto_algs[] to skcipher_algs[].
