From 36650a357eac3e525edbd31db4fe45841b05dc3b Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 28 May 2023 18:20:25 +0200 Subject: binfmt: Slightly simplify elf_fdpic_map_file() There is no point in initializing 'load_addr' and 'seg' here, they are both re-written just before being used below. Doing so, 'load_addr' can be moved in the #ifdef CONFIG_MMU section. Signed-off-by: Christophe JAILLET Acked-by: "Eric W.
