Subject: [PATCH AUTOSEL 4.9 08/21] ARM: samsung: Limit SAMSUNG_PM_CHECK config option to non-Exynos platforms
Date: Fri, 29 Mar 2019 21:30:59 -0400	[thread overview]
Message-ID: <20190330013112.784-8-sashal@kernel.org> (raw)
In-Reply-To: <20190330013112.784-1-sashal@kernel.org>

[ Upstream commit 6862fdf2201ab67cd962dbf0643d37db909f4860 ]

"S3C2410 PM Suspend Memory CRC" feature (controlled by
SAMSUNG_PM_CHECK config option) is incompatible with highmem
(uses phys_to_virt() instead of proper mapping) which is used by
the majority of Exynos boards. The issue manifests itself in OOPS
on affected boards, i.e. on Odroid-U3 I got the following one:

Unable to handle kernel paging request at virtual address f0000000
pgd = 1c0f9bb4
[f0000000] *pgd=00000000

Add PLAT_S3C24XX, ARCH_S3C64XX and ARCH_S5PV210 dependencies to
SAMSUNG_PM_CHECK config option to hide it on Exynos platforms.
