Subject[PATCH] s390: remove DEBUG_MALLOC
From: Pekka Enberg <penberg@cs.helsinki.fi>

The kernel now has kmemleak and kmemtrace so there's no reason to keep
this ugly s390 hack around. I am not sure how it's supposed to work on
SMP anyway as it uses a global variable to temporarily store the return
value of all kmalloc() calls:

void *b;

#define kmalloc(x...) (PRINT_INFO(" kmalloc %p\n",b=kmalloc(x)),b)
