Subject: [PATCH 0/3] arm64/sme: Fixes for SME only support
Date: Tue, 27 Dec 2022 17:12:04 +0000	[thread overview]
Message-ID: <20221223-arm64-fix-sme-only-v1-0-938d663f69e5@kernel.org> (raw)

There is no architectural requirement for systems implementing SME to
also implement SVE, though it is expected to be an unusual configuration.
This series fixes several cases where such systems would encounter
problems, one introduced in the refactoring to avoid disabling SVE over
system call and the other two in signal handling which have been there
since SME was initially supported.
