Subject: [PATCH 05/21] ARM: include: remove unused <asm/processor.h>
Date: Mon, 13 Apr 2020 09:51:48 +0200 [thread overview]
Message-ID: <20200413075204.17544-6-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200413075204.17544-1-a.fatoum@pengutronix.de>
File has been in source tree for 17 years and is unused.
Drop it. The only definition we might want out of the file is
cpu_relax(), which we already open code as barrier() with a comment in a
couple of places. Move the definition to <linux/barebox-wrapper.h>
and drop the file altogether.
No functional change.
