From 2d6cd2a5908adecd06c8cee2a73814463ed71493 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Thu, 25 Dec 2008 13:39:17 +0100 Subject: [PATCH] [S390] remove warnings with functions ending in BUG Functions which end in a BUG() statement and skip the return statement cause compile warnings on s390, e.g.: mm/bootmem.c: In function 'mark_bootmem': mm/bootmem.c:321: warning: control reaches end of non-void function To avoid the warning add an endless loop to the BUG() macro.
