Do you think we can reduce the number of ifndefs by using the functions rte_mem_map, rte_mem_lock?

Why do we need the err flow ifndef'ed?  Isn't it needed in the MP_ALLOC_NATIVE case?

I used rte_mem_xxx APIs in V3. DmitryK pointed out that Apps except unit tests should not use these internal APIs, and also rte_mem_map does not support hugepage with different sized. Given that, decided to work on the mman related part in a future separate patch.

err: is not reachable from the MP_ALLOC_NATIVE.

You are right. Will fix in V11. To avoid the unused err: lable warning, just need to ifndef the err: lable instead of the whole err flow. My mistake.
