Subject: [stable:PATCH v4.14.274 04/27] arm64: Make ARM64_ERRATUM_1188873 depend on COMPAT
Date: Thu, 31 Mar 2022 19:33:37 +0100	[thread overview]
Message-ID: <20220331183400.73183-5-james.morse@arm.com> (raw)
In-Reply-To: <20220331183400.73183-1-james.morse@arm.com>

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.
