From 0378416e6481c3d8a3984cafa910efd4fe6a42e8 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 25 Feb 2022 18:46:58 +0000 Subject: [PATCH] KVM: arm64: Enable Cortex-A510 erratum 2077057 by default [ Upstream commit 4c11113c1a3d10f5b617e5d2b9acd8d1d715450f ] The recently added configuration option for Cortex A510 erratum 2077057 does not have a "default y" unlike other errata fixes. This appears to simply be an oversight since the help text suggests enabling the option if unsure and there's nothing in the commit log to suggest it is intentional.
