Subject: [PATCH v1 2/2] arm64/asm: Remove unused assembler DAIF save/restore macros
Date: Wed, 23 Nov 2022 18:02:09 +0000	[thread overview]
Message-ID: <20221123180209.634650-3-broonie@kernel.org> (raw)
In-Reply-To: <20221123180209.634650-1-broonie@kernel.org>

There are no longer any users of the assembler macros for saving and
restoring DAIF so remove them to prevent further users being added, there
are C equivalents available.
