While building NOMMU and UP following errors show up:

arch/arm/mach-mvebu/pmsu.c: In function 'armada_370_xp_pmsu_idle_enter':
arch/arm/mach-mvebu/pmsu.c:291:2: error: implicit declaration of function 'local_flush_tlb_all' [-Werror=implicit-function-declaration]

Make local_* stuff available for UP (even though it doesn't make
sense) so build can progress.
