From 0391fcb5e1f8f10d4cf491ec2ea107a2e6a937f7 Mon Sep 17 00:00:00 2001 From: Vasily Gorbik Date: Thu, 3 May 2018 16:40:13 +0200 Subject: s390: introduce compile time check for empty .bss section Introduce compile time check for files which should avoid using .bss section, because of the following reasons: - .bss section has not been zeroed yet, - initrd has not been moved to a safe location and could be overlapping with .bss section.
