Use the shadow_root_level from the current MMU as the root level for the PGD, i.e. for VMX's EPTP. This eliminates the weird dependency between VMX and the MMU where both must independently calculate the same root level for things to work correctly. Temporarily keep VMX's calculation of the level and use it to WARN if the incoming level diverges. Opportunistically refactor kvm_mmu_load_pgd() to avoid indentation hell, and rename a 'cr3' param in the load_mmu_pgd prototype that managed to survive the cr3 purge. No functional change intended.

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.
