Matthew Wilcox (Oracle) 350f6bbca1 mm: allow per-VMA locks on file-backed VMAs
Remove the TCP layering violation by allowing per-VMA locks on all VMAs. 
The fault path will immediately fail in handle_mm_fault().  There may be a
small performance reduction from this patch as a little unnecessary work
will be done on each page fault.  See later patches for the improvement.
