Subject: [PATCH v2 2/4] arm64/sme: Fix cut'n'paste in ABI document
Date: Wed, 24 Jan 2024 18:12:36 +0000 [thread overview]
Message-ID: <20240124-arm64-sve-sme-doc-v2-2-fe3964fb3c19@kernel.org> (raw)
In-Reply-To: <20240124-arm64-sve-sme-doc-v2-0-fe3964fb3c19@kernel.org>
The ABI for SME is very like that for SVE so bits of the ABI were copied
but not adequately search and replaced, fix that.
Reported-by: Edmund Grimley-Evans <edmund.grimley-evans@arm.com>
