Subject: [PATCH v3 3/5] ARM: Make CONFIG_CPU_V7 valid for 32bit ARMv8 implementations
Date:   Fri, 18 May 2018 15:39:11 +0100
Message-Id: <20180518143913.26306-4-marc.zyngier@arm.com>
In-Reply-To: <20180518143913.26306-1-marc.zyngier@arm.com>

ARMv8 is a superset of ARMv7, and all the ARMv8 features are
discoverable with a set of ID registers. It means that we can
use CPU_V7 to guard ARMv8 features at compile time.

This commit simply amends the CPU_V7 configuration symbol comment
to reflect that CPU_V7 also covers ARMv8.
