This adds a note in the 17.11 release notes, which applies
only to 17.11-stable backport of the rte_service_finalize()
function. The note should be included in 17.11 notes somewhere.
The fix has a minimal code change in order to workaround the issue.

+* **Secondary processes must call rte_service_finalize to cleanup on exit**
+
+ As ``rte_eal_init()`` now allocates hugepage memory to enable service-cores
+ functionality, there is a requirement for applications to call
+ ``rte_service_finalize()`` to free this memory. Primary processes will
+ re-initialize hugepages - so this does not impact them significantly.
+ Secondary processes which start and stop frequently must call this function,
+ in order to not leak hugepage memory.
