It seems a simple mistake was made when converting follow_hugetlb_page()
over to the VM_FAULT flags bitmasks (in "mm: fault feedback #2", commit
83c54070

).

By using the wrong bitmask, hugetlb_fault() failures are not being
recognized.  This results in an infinite loop whenever follow_hugetlb_page
is involved in a failed fault.
