Outer Shareable and Range TLBI instructions shouldn't be made available to the guest if they are not advertised. Use FGU to disable those, and set HCR_EL2.TLBIOS in the case the host doesn't have FGT. Note that in that later case, we cannot efficiently disable TLBI Range instructions, as this would require to trap all TLBIs.

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.
