As a stepping stone towards deprivileging the host's access to the guest's vCPU structures, introduce some naive flush/sync routines to copy most of the host vCPU into the hyp vCPU on vCPU run and back again on return to EL1. This allows us to run using the pKVM hyp structures when KVM is initialised in protected mode.

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.
