Marc Zyngier 2287a4c1e1 arm64: Expose ID_AA64ISAR1_EL1.XS to sanitised feature consumers
Despite KVM now being able to deal with XS-tagged TLBIs, we still don't
expose these feature bits to KVM.

Plumb in the feature in ID_AA64ISAR1_EL1.

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 reStructuredText 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.
