From bd8676e7bd1c213d944b7c9404615cd7ce02cba4 Mon Sep 17 00:00:00 2001 From: Mark Salter Date: Mon, 4 Nov 2013 11:05:45 -0500 Subject: arm64: use generic RW_DATA_SECTION macro in linker script The .data section in the arm64 linker script currently lacks a definition for page-aligned data. This leads to a .page_aligned section being placed between the end of data and start of bss. This patch corrects that by using the generic RW_DATA_SECTION macro which includes support for page-aligned data.
