From 0e3b186d6ad8768b29ce38f5ee13ab34decc8a34 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Thu, 25 Aug 2022 22:04:56 -0700 Subject: [PATCH] crypto: lib - remove unneeded selection of XOR_BLOCKS CRYPTO_LIB_CHACHA_GENERIC doesn't need to select XOR_BLOCKS. It perhaps was thought that it's needed for __crypto_xor, but that's not the case. Enabling XOR_BLOCKS is problematic because the XOR_BLOCKS code runs a benchmark when it is initialized. That causes a boot time regression on systems that didn't have it enabled before. Therefore, remove this unnecessary and problematic selection.
