Date: Mon, 9 May 2022 15:40:30 +0200 From: Geert Uytterhoeven <geert+renesas@...der.be> To: Catalin Marinas <catalin.marinas@....com>, Will Deacon <will@...nel.org>, Mark Brown <broonie@...nel.org> Cc: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Geert Uytterhoeven <geert+renesas@...der.be> Subject: [PATCH] arm64: ARM Scalable Matrix Extension is ARMv9-A 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.
