The {pmd,pud,pgd}_populate accessors usage have always been a bit weird
in KVM. We don't have a struct mm to pass (and neither does the kernel
most of the time, but still...), and the 32bit code has all kind of
cache maintenance that doesn't make sense on ARMv7+ when MP extensions
are mandatory (which is the case when the VEs are present).
Let's bite the bullet and provide our own implementations. The only bit
of architectural code left has to do with building the table entry
itself (arm64 having up to 52bit PA, arm lacking PUD level).

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
