With TRANSPARENT_HUGEPAGE_PUD enabled the kernel can find huge PUD entries. Add a helper to move huge PUD entries on mremap(). This will be used by a later patch to optimize mremap of PUD_SIZE aligned level 4 PTE mapped address This also make sure we support mremap on huge PUD entries even with CONFIG_HAVE_MOVE_PUD disabled.

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.
