+Subject: memblock: allow zero threshold in validate_numa_converage()
+
+From: Mike Rapoport (Microsoft) <rppt@kernel.org>
+
+commit 9cdc6423acb49055efb444ecd895d853a70ef931 upstream.
+
+Currently memblock validate_numa_converage() returns false negative when
+threshold set to zero.
+
+Make the check if the memory size with invalid node ID is greater than
+the threshold exclusive to fix that.
