Subject: [PATCH AUTOSEL 5.7 54/54] arm64: Allow booting of late CPUs affected by erratum 1418040
Date: Mon, 24 Aug 2020 12:36:33 -0400 [thread overview]
Message-ID: <20200824163634.606093-54-sashal@kernel.org> (raw)
In-Reply-To: <20200824163634.606093-1-sashal@kernel.org>
From: Marc Zyngier <maz@kernel.org>
[ Upstream commit bf87bb0881d0f59181fe3bbcf29c609f36483ff8 ]
As we can now switch from a system that isn't affected by 1418040
to a system that globally is affected, let's allow affected CPUs
to come in at a later time.
