From cedbecd60a8effc66dc8bed4e5489ff9365c9b19 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Fri, 23 May 2014 13:18:27 +0200 Subject: s390/boot: fix boot of compressed kernel built with gcc 4.9 Add -fno-delete-null-pointer-checks to CFLAGS for the code in arch/s390/boot. Without the option a compressed kernel built with gcc 4.9 won't boot.
