The VCMDQ in the tegra241-cmdqv driver has a guest mode that supports only a few invalidation commands. A batch is initialized with a cmdq, so it has to confirm whether a new command is supported or not. Add a supports_cmd function pointer to the cmdq structure, where the vcmdq driver should hook a command scan function. Add an inline helper too so it can be used by both sides. If a new command is not supported, simply issue the existing batch and re- init it as a new batch.

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.
