Subject: [PATCH v2 0/6] arm64/sme: Collected SME fixes
Date: Wed, 04 Dec 2024 15:20:48 +0000 [thread overview]
Message-ID: <20241204-arm64-sme-reenable-v2-0-bae87728251d@kernel.org> (raw)
This series collects the various SME related fixes that were previously
posted separately. These should address all the issues I am aware of so
a patch which reenables the SME configuration option is also included.
Signed-off-by: Mark Brown <broonie@kernel.org>

Changes in v2:
- Pull simplification of the signal restore code after the SME
reenablement, it's not a fix but there's some code overlap.
- Comment updates.
- Link to v1: https://lore.kernel.org/r/20241203-arm64-sme-reenable-v1-0-d853479d1b77@kernel.org
