From 5e1e087457c94ad7fafbe1cf6f774c6999ee29d4 Mon Sep 17 00:00:00 2001 From: Zenghui Yu Date: Tue, 9 Aug 2022 12:38:48 +0800 Subject: [PATCH] arm64: Fix match_list for erratum 1286807 on Arm Cortex-A76 Since commit 51f559d66527 ("arm64: Enable repeat tlbi workaround on KRYO4XX gold CPUs"), we failed to detect erratum 1286807 on Cortex-A76 because its entry in arm64_repeat_tlbi_list[] was accidently corrupted by this commit. Fix this issue by creating a separate entry for Kryo4xx Gold.
