This patch adds VAS window allocatioa/close with the corresponding hcalls. Also changes to integrate with the existing user space VAS API and provide register/unregister functions to NX pseries driver. The driver register function is used to create the user space interface (/dev/crypto/nx-gzip) and unregister to remove this entry. The user space process opens this device node and makes an ioctl to allocate VAS window. The close interface is used to deallocate window.

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.
