The set of patches add IBM Power architecture to the DPDK. It adds the required support to the EAL library. This set of patches doesn't support full DPDK function on Power processors. To compile on PPC64 architecture, GCC version >= 4.8 must be used. According to Bruce and Neil's comments, this v5 patch removed the common configuration files of Powerpc in v4. Also, it fixed the checkpatch issues in v3.
The only unsolved checkpatch issue is : ERROR: space prohibited before open square bracket '[' This issue refers to the asm code input/output naming. But I think the error is invalid.
