Since the hypervisor always uses 4K as its page size, the size of PFNs used for gpadl should be HV_HYP_PAGE_SIZE rather than PAGE_SIZE, so adjust this accordingly as the preparation for supporting 16K/64K page size guests. No functional changes on x86, since PAGE_SIZE is always 4k (equals to HV_HYP_PAGE_SIZE).

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.
