Subject: [PATCH v6 05/21] arm64: compat: change config dependences to aarch32
Date: Thu, 14 Jan 2016 20:23:02 +0300 [thread overview]
Message-ID: <1452792198-10718-6-git-send-email-ynorov@caviumnetworks.com> (raw)
In-Reply-To: <1452792198-10718-1-git-send-email-ynorov@caviumnetworks.com>
From: Bamvor Jian Zhang <bamvor.zhangjian@linaro.org>
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.
