Stanislav Kinsburskiy 364adc45e9 clocksource: hyper-v: Use TSC PFN getter to map vvar page
Instead of converting the virtual address to physical directly.

This is a precursor patch for the upcoming support for TSC page mapping into
Microsoft Hypervisor root partition, where TSC PFN will be defined by the
hypervisor and thus can't be obtained by linear translation of the physical
address.

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.
