Subject: [PATCH 2/3] ARM: turn arm_mem_stack_top into a macro
Date: Thu,  2 Dec 2021 08:42:55 +0100	[thread overview]
Message-ID: <20211202074256.200325-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20211202074256.200325-1-a.fatoum@pengutronix.de>

This makes it possible to use for static initialization, like done in a
follow-up commit.
