Move the common check-and-set handling of PAT MSR writes out of vendor code and into kvm_set_msr_common(). This aligns writes with reads, which are already handled in common code, i.e. makes the handling of reads and writes symmetrical in common code. Alternatively, the common handling in kvm_get_msr_common() could be moved to vendor code, but duplicating code is generally undesirable (even though the duplicatated code is trivial in this case), and guest writes to PAT should be rare, i.e. the overhead of the extra function call is a non-issue in practice.

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.
