Subject: [PATCH AUTOSEL 5.9 21/21] arm64: cpu_errata: Apply Erratum 845719 to KRYO2XX Silver
Date: Tue, 17 Nov 2020 07:56:52 -0500 [thread overview]
Message-ID: <20201117125652.599614-21-sashal@kernel.org> (raw)
In-Reply-To: <20201117125652.599614-1-sashal@kernel.org>
From: Konrad Dybcio <konrad.dybcio@somainline.org>
[ Upstream commit 23c216416056148136bdaf0cdd18caf4904bb6e1 ]
QCOM KRYO2XX Silver cores are Cortex-A53 based and are
susceptible to the 845719 erratum. Add them to the lookup
list to apply the erratum.
