Subject: [PATCH v2 0/7] MIPS: arch_numa enablement

Hi all,

This series enabled arch_numa for generic MIPS machine, and ported
loongson64 machine to arch_numa infra. SGI IP27 is left untouched
with legacy NUMA implementation as I don't have access to hardware.

Tested on Loongson64 NUMA system and numa_emu on Boston.

Please review.

Thanks
