Save and restore the new per-size hugepage enabled setting, if available on the running kernel. Since the number of per-size directories is not fixed, solve this as simply as possible by catering for a maximum number in the thp_settings struct (20). Each array index is the order. The value of THP_NEVER is changed to 0 so that all of these new settings default to THP_NEVER and the user only needs to fill in the ones they want to enable.

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.
