Replace a modulo operator with the more common pattern for computing the
gfn "offset" of a huge page to fix an i386 build error.

  arch/x86/kvm/mmu/tdp_mmu.c:212: undefined reference to `__umoddi3'

In fact, almost all of tdp_mmu.c can be elided on 32-bit builds, but
that is a much larger patch.

Fixes: 2f2fad08

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.
