Hyper-V MSR-Bitmap tests do RDMSR from L2 to exit to L1. While 'evmcs_test' correctly clobbers all GPRs (which are not preserved), 'hyperv_svm_test' does not. Introduce a more generic rdmsr_from_l2() to avoid code duplication and remove hardcoding of MSRs. Do not put it in common code because it is really just a selftests bug rather than a processor feature that requires it.

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.
