Subject: [PATCH AUTOSEL 5.9 20/21] arm64: kpti: Add KRYO2XX gold/silver CPU cores to kpti safelist
Date: Tue, 17 Nov 2020 07:56:51 -0500 [thread overview]
Message-ID: <20201117125652.599614-20-sashal@kernel.org> (raw)
In-Reply-To: <20201117125652.599614-1-sashal@kernel.org>
From: Konrad Dybcio <konrad.dybcio@somainline.org>
[ Upstream commit e3dd11a9f2521cecbcf30c2fd17ecc5a445dfb94 ]
QCOM KRYO2XX gold (big) silver (LITTLE) CPU cores are based on
Cortex-A73 and Cortex-A53 respectively and are meltdown safe,
hence add them to kpti_safe_list[].
