Add x86-64 hugepage support in the form of a x86-only variant of virt_pg_map() that takes an explicit page size. To keep things simple, follow the existing logic for 4k pages and disallow creating a hugepage if the upper-level entry is present, even if the desired pfn matches. Opportunistically fix a double "beyond beyond" reported by checkpatch.

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.
