[ Upstream commit1dfc3e9050] As it currently stands, KVM makes use of FEAT_HAFDBS unconditionally. Use of the feature in the rest of the kernel is guarded by an associated Kconfig option. Align KVM with the rest of the kernel and only enable VTCR_HA when ARM64_HW_AFDBM is enabled. This can be helpful for testing changes to the stage-2 access fault path on Armv8.1+ implementations.

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.
