[Xen-devel] [RFC PATCH v3 07/24] ARM: NUMA: Add existing ARM numa code under CONFIG_NUMA

[vijay.kilari@xxxxxxxxx]

From: Vijaya Kumar K <Vijaya.Kumar@xxxxxxxxxx>

Right now CONFIG_NUMA is not enabled for ARM and
existing code in asm-arm/numa.h is for !CONFIG_NUMA.
Hence put this code under #ifndef CONFIG_NUMA.

This help to make this changes work when CONFIG_NUMA
is not enabled. Though CONFIG_NUMA is enabled by default,
manually disabling this option is possible and compilation
should go through. Hence kept the these changes under
!CONFIG_NUMA.
