[dpdk-dev] [PATCH v4] arch/arm: optimization for memcpy on AArch64

This patch provides an option to do rte_memcpy() using 'restrict' qualifier, which can induce GCC to do optimizations by using more efficient instructions, providing some performance gain over memcpy() on some AArch64 platforms/enviroments. The memory copy performance differs between different AAr
