Add a helper to set a vCPU's guest.MAXPHYADDR, and use it in the test that verifies the emulator returns an error on an unknown instruction when KVM emulates in response to an EPT violation with a GPA that is legal in hardware but illegal with respect to the guest's MAXPHYADDR. Add a helper even though there's only a single user at this time. Before its removal, mmu_role_test also stuffed guest.MAXPHYADDR, and the helper provides a small amount of clarity. More importantly, this eliminates a set_cpuid() user and an instance of modifying kvm_get_supported_cpuid()'s static "cpuid".

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.
