Subject: [PATCH 2/4] arm64: Make ARM64_ERRATUM_1188873 depend on COMPAT
Date: Mon,  8 Apr 2019 17:02:14 +0100	[thread overview]
Message-ID: <20190408160216.223871-3-marc.zyngier@arm.com> (raw)
In-Reply-To: <20190408160216.223871-1-marc.zyngier@arm.com>

Since ARM64_ERRATUM_1188873 only affects AArch32 EL0, it makes some
sense that it should depend on COMPAT.
