This was a mistake on fix tag. 
The patch changed two lines of code. Fix tag was generated for both of the lines which involves two commits.
However, issue was introduced by only the later patch.

Discussion in the thread:
http://patches.dpdk.org/patch/71351/
Because one of bug fix patch in the patch needed to be backported, and it was
hard to use rte_atomic* API to do the fix, so C11 atomic built-in was used. To keep code in stable
release clean, decision was made to backport all other patches in the patch set that involves
C11 atomic built-in.
