[PATCH 12/25] arm64: compat: change config dependences to aarch32

From: Yury Norov <hidden>
Date: 2016-04-05 22:11:45
Also in: linux-arch, linux-s390, lkml
Subsystem: arm64 port (aarch64 architecture), the rest · Maintainers: Catalin Marinas, Will Deacon, Linus Torvalds

From: Bamvor Jian Zhang <redacted>

With the patches of ILP32, COMPAT is not equivalent to AARCH32 in EL0.
This patch fix this by updating the dependency from COMPAT to
AARCH32_EL0 for ARMV8_DEPRECATED and ARM64_ERRATUM_845719.
