[ Upstream commit cddba0af0b7919e93134469f6fdf29a7d362768a ]
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.
