Suzuki K Poulose 61fa5a867b kvm: arm64: Make stage2 page table layout dynamic
Switch to dynamic stage2 page table layout based on the given
VM. So far we had a common stage2 table layout determined at
compile time. Make decision based on the VM instance depending
on the IPA limit for the VM. Adds helpers to compute the stage2
parameters based on the guest's IPA and uses them to make the decisions.

The IPA limit is still fixed to 40bits and the build time check
to ensure the stage2 doesn't exceed the host kernels page table
levels is retained. Also make sure that we use the pud/pmd level
helpers from the host only when they are not folded.

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.
