Jani Nikula 1af13bc6d0 drm/i915/vblank: add and use intel_de_read64_2x32() to read vblank counter
Add intel_de_read64_2x32() wrapper for the uncore version of the same,
and use it to read the high and low frame registers. Avoid duplicating
code for existing helpers.

The slight functional difference is checking that the entire high
register remains the same across two reads, instead of just the part
we're interested in. This should be of no consequence. (Unless those
bits function as a PRNG.)

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.
