Subject: Fix VM_FAULT flags conversion for hugetlb
From: Adam Litke <agl@xxxxxxxxxx>
It seems a simple mistake was made when converting follow_hugetlb_page()
over to the VM_FAULT flags bitmask stuff:
(commit 83c54070ee1a2d05c89793884bea1a03f2851ed4).
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.
