Subject: [PATCH v5 7/9] kselftest/arm64: Handle FPMR context in generic signal frame parser
Date: Wed, 06 Mar 2024 23:14:52 +0000	[thread overview]
Message-ID: <20240306-arm64-2023-dpisa-v5-7-c568edc8ed7f@kernel.org> (raw)
In-Reply-To: <20240306-arm64-2023-dpisa-v5-0-c568edc8ed7f@kernel.org>

Teach the generic signal frame parsing code about the newly added FPMR
frame, avoiding warnings every time one is generated.
