Subject: [PATCH 15/15] ARM: l2c: replace open coded VA->PA calculation
Date: Sat, 5 Aug 2017 21:52:22 +0100 [thread overview]
Message-ID: <20170805205222.19868-16-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20170805205222.19868-1-ard.biesheuvel@linaro.org>
This replaces an open coded calculation to obtain the physical
address of a far symbol with a call to the new adr_l macro.
