  Hugetlb vmemmap default option (HUGETLB_PAGE_OPTIMIZE_VMEMMAP_DEFAULT_ON)
is a sub-option to hugetlbfs, but it shows in the same level as hugetlbfs
itself, under "Pesudo filesystems".

Make the vmemmap option a sub-option to hugetlbfs, by changing hugetlbfs
into a menuconfig.  When moving it, fix a typo 'v' spot by Randy.
