    Subject[PATCH 5.19 137/158] arm64: Fix match_list for erratum 1286807 on Arm Cortex-A76
    Date
    From: Zenghui Yu <yuzenghui@huawei.com>

    commit 5e1e087457c94ad7fafbe1cf6f774c6999ee29d4 upstream.

    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.

    Fixes: 51f559d66527 ("arm64: Enable repeat tlbi workaround on KRYO4XX gold CPUs")
