In preparation for handling cache maintenance of guest pages from within the pKVM hypervisor at EL2, introduce an EL2 copy of icache_inval_pou() which will later be plumbed into the stage-2 page-table cache maintenance callbacks, ensuring that the initial contents of pages mapped as executable into the guest stage-2 page-table is visible to the instruction fetcher.

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.
