Before GICv4.1, we don't have direct access to the VLPI state. So we simply let it fail early when encountering any VLPI in saving. But now we don't have to return -EACCES directly if on GICv4.1. Let’s change the hard code and give a chance to save the VLPI state (and preserve the UAPI).

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.
