[PATCH] ARM: mm/alignment.c: Fix build error

[Fabio Estevam]

If CONFIG_PROC_FS is not set the following error is generated because
'cpu_is_v6_unaligned' definition is protected by CONFIG_PROC_FS:

CC      arch/arm/mm/alignment.o
arch/arm/mm/alignment.c: In function 'alignment_init':
arch/arm/mm/alignment.c:964: error: implicit declaration of function 'cpu_is_v6_unaligned'
arch/arm/mm/alignment.c:968: error: implicit declaration of function 'safe_usermode'
make[1]: *** [arch/arm/mm/alignment.o] Error 1
make: *** [arch/arm/mm] Error 2

This build error was triggered by 'make randconfig'.

The same patch from Arnd is already queued by RMK.
