Right not CONFIG_NUMA is not enabled for ARM and
s/not/now/
existing code in asm-arm/numa.h is for !COFIG_NUMA.
s/COFIG_NUMA/CONFIG_NUMA/
Hence put this code under #ifndef CONFIG_NUMA.
This help to make this changes work when CONFIG_NUMA
is not enabled.
Is there any reason to let the choice to the user to enable/disable NUMA?
Also define NODES_SHIFT macro for ARM.
