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]
local_flush_tlb_all();
^
CC arch/arm/mach-omap2/control.o
cc1: some warnings being treated as errors
make[1]: *** [arch/arm/mach-mvebu/pmsu.o] Error 1

...

arch/arm/mach-imx/pm-imx5.c: In function 'mx5_suspend_enter':
arch/arm/mach-imx/pm-imx5.c:227:3: error: implicit declaration of function 'local_flush_tlb_all' [-Werror=implicit-function-declaration]
local_flush_tlb_all();

arch/arm/mach-imx/pm-imx6.c: In function 'imx6q_suspend_finish':
arch/arm/mach-imx/pm-imx6.c:354:3: error: implicit declaration of function 'local_flush_tlb_all' [-Werror=implicit-function-declaration]
local_flush_tlb_all();
^
cc1: some warnings being treated as errors
make[1]: *** [arch/arm/mach-imx/pm-imx6.o] Error 1

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