Create some common API's for adding entries to a xa_mmap. Searching for an entry and freeing one. The general approach is copied from the EFA driver and improved to be more general and do more to help the drivers. Integration with the core allows a reference counted scheme with a free function so that the driver can know when its mmaps are all gone. This significant new functionality will be helpful for drivers to have the correct lifetime model for mmap objects.

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.
