The feature of minimizing overhead of struct page associated with each HugeTLB page is implemented on x86_64, however, the infrastructure of this feature is already there, we could easily enable it for other architectures. Introduce ARCH_WANT_HUGETLB_PAGE_FREE_VMEMMAP for other architectures to be easily enabled. Just select this config if they want to enable this feature.

README
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.
