From 2edbdfc89d9f4077d5255defe843248170013b3b 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 commit 874b301985ef2f89b8b592ad255e03fb6fbfe605 upstream. 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.
