While building for NOMMU several link time issues were seen:

mm/built-in.o: In function `do_mmu_notifier_register':
usercopy.c:(.text+0x34d10): undefined reference to `mm_take_all_locks'
usercopy.c:(.text+0x34d9c): undefined reference to `mm_drop_all_locks'

It seems that Infiniband assumes that is it used in MMU configurations
only, so add dependency on CONFUG_MMU.
