Stephen, can you squash in the following for the time being?

diff --git a/mm/memory.c b/mm/memory.c
index feff48e1465a..15cbd10afd59 100644
--- a/mm/memory.c
+++ b/mm/memory.c
@@ -4775,6 +4775,7 @@ int follow_pte(struct mm_struct *mm, unsigned long
return -EINVAL;

* follow_pfn - look up PFN at a user virtual address
A similar patch has been posted already, but Jason Gunthorpe asked to
add some kerneldoc comments. Therefore it will not be in kvm/next for a
few more days.
