The patch titled
     Subject: mm/memblock: use WARN_ONCE when MAX_NUMNODES passed as input parameter
has been removed from the -mm tree.  Its filename was
     mm-memblock-use-warn_once-when-max_numnodes-passed-as-input-parameter.patch

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: mm/memblock: use WARN_ONCE when MAX_NUMNODES passed as input parameter

Check nid parameter and produce warning if it has deprecated MAX_NUMNODES
value.  Also re-assign NUMA_NO_NODE value to the nid parameter in this
case.

These will help to identify the wrong API usage (the caller) and make code
simpler.
