Subject: [PATCH 4.14 15/31] ARM: use LOADADDR() to get load address of sections
Date: Thu, 10 Mar 2022 15:18:28 +0100	[thread overview]
Message-ID: <20220310140807.979965576@linuxfoundation.org> (raw)
In-Reply-To: <20220310140807.524313448@linuxfoundation.org>

From: "Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>

commit 8d9d651ff2270a632e9dc497b142db31e8911315 upstream.

Use the linker's LOADADDR() macro to get the load address of the
sections, and provide a macro to set the start and end symbols.
