Subject: [PATCH] arm64: ARM Scalable Matrix Extension is ARMv9-A
Date:   Mon,  9 May 2022 15:40:30 +0200
Message-Id: <df002b0ff3cb89954d5a2c39a5dd8528d45771f3.1652103603.git.geert+renesas@glider.be>

The help text for the config option to enable support for the ARM
Scalable Matrix Extension does not mention the specification baseline
for this extension.  Make it clear this is an extension for the ARMv9-A
architecture, so users know when it is safe to disable this option,
which is enabled by default.

Fixes: a1f4ccd25cc25625 ("arm64/sme: Provide Kconfig for SME")
