Subject: [PATCH v2 0/6] arm64/sme: Collected SME fixes

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@...nel.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
