This patchset fixes performance/cache resource issues with 128-byte cache line targets
found in mbuf and bitmap DPDK libraries

Currently, we have two DPDK targets(ThunderX and ppc_64) which are based on
128-bytes cache line size target.

This patchset doesn't introduce any performance degradation
for 64-bytes cache line size targets.

  mbuf: fix performance/cache resource issue with 128-byte cache line
    targets
  bitmap: optimize for 128-bytes cache line targets
