Subject: [PATCH 5/9] pbl: Alias memcpy and memset
Date: Fri, 18 Sep 2020 10:45:28 +0200 [thread overview]
Message-ID: <20200918084532.2794-6-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200918084532.2794-1-s.hauer@pengutronix.de>
With KASan the memcpy/memset functions are instrumented as well, but
some code will still have to call the non instrumented versions __memcpy
and __memset. Add aliases for them to PBL to make them available.
