mainline inclusion from mainline-v5.19-rc1 commit 02436762f5ff4b3f662bc196c70a563bcbc92b7d category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I50ABL CVE: NA
Reference: https://patchwork.kernel.org/project/linux-crypto/patch/20220315094454.45269...
--------------------------------
The subsequent patches of the series will have an implementation of SM4-ECB/CBC/CFB/CTR accelerated by the CE instruction set, which conflicts with the current module name. In order to keep the naming rules of the AES algorithm consistent, the sm4-ce algorithm is renamed to sm4-ce-cipher.
In addition, the speed of sm4-ce-cipher is better than that of SM4 NEON. By the way, the priority of the algorithm is adjusted to 300, which is also to leave room for the priority of SM4 NEON.
