Naoya Horiguchi 25ee01a2fc mm: hugetlb: proc: add hugetlb-related fields to /proc/PID/smaps ...

Currently /proc/PID/smaps provides no usage info for vma(VM_HUGETLB),
which is inconvenient when we want to know per-task or per-vma base
hugetlb usage.  To solve this, this patch adds new fields for hugetlb
usage like below:
