Subject: [PATCH AUTOSEL 5.10 02/19] ARM: rockchip: Use memcpy_toio instead of memcpy on smp bring-up
Date: Mon, 20 Dec 2021 20:58:57 -0500 [thread overview]
Message-ID: <20211221015914.116767-2-sashal@kernel.org> (raw)
In-Reply-To: <20211221015914.116767-1-sashal@kernel.org>
From: "Ivan T. Ivanov" <iivanov@suse.de>
[ Upstream commit 423e85e97aaf69e5198bbec6811e3825c8b5019a ]
This fixes a potential kernel panic on memcpy when FORTIFY_SOURCE
is enabled. Because memory is iomem use appropriate function for
accessing it.
