Subject: [PATCH 4.14 04/27] arm64: Make ARM64_ERRATUM_1188873 depend on COMPAT
Date: Fri, 1 Apr 2022 08:36:14 +0200 [thread overview]
Message-ID: <20220401063624.358469645@linuxfoundation.org> (raw)
In-Reply-To: <20220401063624.232282121@linuxfoundation.org>
From: Marc Zyngier <marc.zyngier@arm.com>
commit c2b5bba3967a000764e9148e6f020d776b7ecd82 upstream.
Since ARM64_ERRATUM_1188873 only affects AArch32 EL0, it makes some
sense that it should depend on COMPAT.
