Currently the SVM get_attr call allows querying, which flags are set in the entire address range. Add the opposite query, which flags are clear in the entire address range. Both queries can be combined in a single get_attr call, which allows answering questions such as, "is this address range coherent, non-coherent, or a mix of both"?

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.
