[PATCH] kill mm_struct.used_hugetlb
mm_struct.used_hugetlb used to eliminate costly find_vma() from
follow_page(). Now it is used only in ia64 version of follow_huge_addr().
I know nothing about ia64, but this REGION_NUMBER() looks simple enough to
kill used_hugetlb.
There is debug version (commented out) of follow_huge_addr() in i386 which
looks at used_hugetlb, but it can work without this check.
