+Subject: ARM: mm: Avoid ABI change in 3.13.6
+Forwarded: not-needed
+
+struct mem_type gained a new member in 3.13.6, and there are two
+exported functions that take/return pointers to this structure.
+However the actual definition is opaque to modules, so this is not an
+ABI change and we can just hide it from genksyms.
