Vitaly Kuznetsov 2cf0284223 x86/hyperv: Check frequency MSRs presence according to the specification
Hyper-V TLFS specifies two bits which should be checked before accessing
frequency MSRs:

- AccessFrequencyMsrs (BIT(11) in EAX) which indicates if we have access to
  frequency MSRs.
- FrequencyMsrsAvailable (BIT(8) in EDX) which indicates is these MSRs are
  present.
  
Rename and specify these bits accordingly.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
