Subject[PATCH] mm: Suppress mm/memory.o warning on older compilers if !CONFIG_NUMA_BALANCING
The kbuild test robot reported the following after the merge of Automatic
NUMA Balancing when cross-compiling for avr32.

mm/memory.c: In function 'do_pmd_numa_page':
mm/memory.c:3593: warning: no return statement in function returning non-void

The code is unreachable but the avr32 cross-compiler was not new enough
to know that. This patch suppresses the warning.
