[PATCH] s390: BUG() warnings
Use __builtin_trap instead of an inline assembly in the BUG() macro. That way the compiler knows that BUG() won't return. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
