Marc Zyngier 6673047405 KVM: arm64: Mask out non-VA bits from TLBI VA* on VNCR invalidation
When handling a TLBI VA* instruction that potentially targets a
VNCR page mapping, we fail to mask out the top bits that contain
the ASID and TTL fields, hence potentially failing the VA check
in the TLB code.

An additional wrinkle is that we fail to sign extend the VA,
again leading to failed VA checks.

Fix both in one go by sign-extending the VA from bit 48, making
it comparable to the way we interpret VNCR_EL2.BADDR.

Fixes: 4ffa72ad8f ("KVM: arm64: nv: Add S1 TLB invalidation primitive for VNCR_EL2")

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.
