This is an independent bug, nothing to do with the NUMA stuff. Fixed
in my tree now (commit 3587b1b097d70).

Of course, it's entirely possible that the NUMA patches are subtly
buggy and helped trigger the fanotify OVERFLOW event that had this
particular bug. But the oops itself is due to a real bug.
