From 2e9440ae6eab492572463d8cb266381264867723 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 5 Jan 2021 17:47:55 +0100 Subject: crypto: x86/serpent - drop CTR mode implementation Serpent in CTR mode is never used by the kernel directly, and is highly unlikely to be relied upon by dm-crypt or algif_skcipher. So let's drop the accelerated CTR mode implementation, and instead, rely on the CTR template and the bare cipher.
