I saw a bunch of similar errors on 3.14.x up to and including 3.14.4,
running Java (Tomcat) and Postgres on Xen PV. Have not seen it since
"mm: use paravirt friendly ops for NUMA hinting ptes" landed in 3.14.5.
402e194dfc5b38d99f9c65b86e2666b29adebf8c in stable,
29c7787075c92ca8af353acd5301481e6f37082f upstream
As I did not follow the original discussion I have no idea if this is
the same thing, and I'm way too lazy to look for it now. ;-)
