I tried cherry-picking this on top of 3.2.17, but there was a conflict
in unmap_ref_private().  It looks like all of these belong in 3.2.y as
well:

1e16a53 mm/hugetlb.c: fix virtual address handling in hugetlb fault
0c176d5 mm: hugetlb: fix pgoff computation when unmapping page from vma
ea5768c mm/hugetlb.c: avoid bogus counter of surplus huge page
409eb8c mm/hugetlb.c: undo change to page mapcount in fault handler
cd2934a flush_tlb_range() needs ->page_table_lock when ->mmap_sem is not held

Sorry, I didn't make myself clear.  I'm asking for confirmation: should
these all be applied to 3.2.y?

I think yes, probably, but I'm not enough of an expert on the
hugetlbfs code to say for sure.  David Gibson is on leave at the
moment and so may not be in a position to reply.  Perhaps one of
hugetlbfs experts on cc could reply?
