[ 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
