Kunkun Jiang 21bc72eef0 KVM: arm64: vgic-its: Clear ITE when DISCARD frees an ITE 
commit 7602ffd1d5 upstream.

When DISCARD frees an ITE, it does not invalidate the
corresponding ITE. In the scenario of continuous saves and
restores, there may be a situation where an ITE is not saved
but is restored. This is unreasonable and may cause restore
to fail. This patch clears the corresponding ITE when DISCARD
frees an ITE.

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 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.
