Ard Biesheuvel 5a6520493c arm64/kvm: Configure HYP TCR.PS/DS based on host stage1 
commit f0da16992a upstream.

When the host stage1 is configured for LPA2, the value currently being
programmed into TCR_EL2.T0SZ may be invalid unless LPA2 is configured
at HYP as well.  This means kvm_lpa2_is_enabled() is not the right
condition to test when setting TCR_EL2.DS, as it will return false if
LPA2 is only available for stage 1 but not for stage 2.

Similary, programming TCR_EL2.PS based on a limited IPA range due to
lack of stage2 LPA2 support could potentially result in problems.

So use lpa2_is_enabled() instead, and set the PS field according to the
host's IPS, which is capped at 48 bits if LPA2 support is absent or
disabled. Whether or not we can make meaningful use of such a
configuration is a different question.

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 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.
