While KHO exposes folio as the primitive externally, internally its
restoration machinery operates on pages. This can be seen with
kho_restore_folio() for example. It performs some sanity checks and hands
it over to kho_restore_page() to do the heavy lifting of page restoration.
After the work done by kho_restore_page(), kho_restore_folio() only
converts the head page to folio and returns it. Similarly,
deserialize_bitmap() operates on the head page directly to store the
order.
Move the sanity checks for valid phys and order from the public-facing
kho_restore_folio() to the private-facing kho_restore_page(). This makes
the boundary between page and folio clearer from KHO's perspective.
While at it, drop the comment above kho_restore_page(). The comment is
misleading now. The function stopped looking like free_reserved_page()

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 reStructuredText 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.
