Subject: [PATCH v7 16/31] arm64: cpucaps: Rename GICv3 CPU interface capability
Date: Thu, 03 Jul 2025 12:25:06 +0200	[thread overview]
Message-ID: <20250703-gicv5-host-v7-16-12e71f1b3528@kernel.org> (raw)
In-Reply-To: <20250703-gicv5-host-v7-0-12e71f1b3528@kernel.org>

In preparation for adding a GICv5 CPU interface capability,
rework the existing GICv3 CPUIF capability - change its name and
description so that the subsequent GICv5 CPUIF capability
can be added with a more consistent naming on top.
