Subject: [PATCH v3 17/21] kselftest/arm64: Handle FPMR context in generic signal frame parser
Date: Tue, 05 Dec 2023 16:48:15 +0000 [thread overview]
Message-ID: <20231205-arm64-2023-dpisa-v3-17-dbcbcd867a7f@kernel.org> (raw)
In-Reply-To: <20231205-arm64-2023-dpisa-v3-0-dbcbcd867a7f@kernel.org>
Teach the generic signal frame parsing code about the newly added FPMR
frame, avoiding warnings every time one is generated.
