Date: Thu, 10 Mar 2022 15:19:16 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Catalin Marinas <catalin.marinas@....com>, "Russell King (Oracle)" <rmk+kernel@...linux.org.uk> Subject: [PATCH 5.4 15/33] ARM: use LOADADDR() to get load address of sections From: "Russell King (Oracle)" <rmk+kernel@...linux.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.
