+Subject: [PATCH] xen: Fix {set,clear}_foreign_p2m_mapping on autotranslating
+ guests
+
+Commit 82616f9599a7 ("xen: remove tests for pvh mode in pure pv paths")
+removed the check for autotranslation from {set,clear}_foreign_p2m_mapping
+but those are called by grant-table.c also on PVH/HVM guests.
