Subject: 	[dpdk-dev] [PATCH] PPC: Fix NUMA node numbering on IBM POWER8 
LE machine

When Linux is running on bare metal, it gets the raw hardware
information. On POWER8 little endian bare metal machine, the node number
is not continuous. It will jump from 0 to other values, for example, it
can be 0, 1, 16, 17. This patch modified the CONFIG_RTE_MAX_NUMA_NODES
value to make dpdk work on POWER8 bare metal little endian machine.
