The KVM patching callbacks use cpus_have_final_cap() internally within has_vhe(), and subsequent patches will make it invalid to call cpus_have_final_cap() before alternatives patching has completed, and will mean that cpus_have_const_cap() will always fall back to dynamic checks prior to alternatives patching. In preparation for said change, this patch modifies the KVM patching callbacks to use cpus_have_cap() directly. This is not subject to patching, and will dynamically check the cpu_hwcaps array, which is functionally equivalent to the existing behaviour. There should be no functional change as a result of this patch.

README
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.
