From 6de299230fa63d3865501b069657ac26cedebd9a Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Tue, 10 Mar 2020 10:15:04 +0100 Subject: [PATCH] arm: set the relocated gd with gd->new_gd Simplify the arm relocation behavior and get gd directly form new_gd, as it is already done in crt0_64.S: ldr x18, [x18, #GD_NEW_GD] /* x18 <- gd->new_gd */ This patch avoid assumption on new GD location (new GD is below bd - with #GD_SIZE offset).
