+Subject: [PATCH 8/8] xen/arm: mm: Do not dump the p2m when mapping a foreign
+ gfn
+
+The physmap operation XENMAPSPACE_gfmn_foreign is dumping the p2m when
+an error occured by calling dump_p2m_lookup. But this function is not
+using ratelimited printk.
+
+Any domain able to map foreign gfmn would be able to flood the Xen
+console.
+
+The information wasn't not useful so drop it.
+
+This is XSA-141.
