Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc
ppc44x_defconfig) produced these warnings:

ipc/util.c: In function 'ipc_init':
ipc/util.c:105:2: warning: statement with no effect [-Wunused-value]
mm/slub.c: In function 'kmem_cache_init':
mm/slub.c:3600:2: warning: statement with no effect [-Wunused-value]

Introduced by commit 23e9e430f87e ("include/linux/memory.h: implement
register_hotmemory_notifier()").
