Subject: [PATCH v2 07/20] asm: unaligned: don't do unaligned accesses
Date: Tue, 16 Mar 2021 09:04:52 +0100	[thread overview]
Message-ID: <20210316080505.19361-8-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210316080505.19361-1-a.fatoum@pengutronix.de>

While HW can emulate unaligned accesses at a performance penalty,
it's probably best to just not generate them.
