+From: Jan Beulich <jbeulich%suse.com@localhost>
+Subject: memory: fix off-by-one in XSA-346 change
+
+The comparison against ARRAY_SIZE() needs to be >= in order to avoid
+overrunning the pages[] array.
+
+This is XSA-355.
+
+Fixes: 5777a3742d88 ("IOMMU: hold page ref until after deferred TLB flush")
