This patch intoruduces a new mlx5_ib driver attribute to the DM allocation method - the DM type. In order to allow addition of new types in downstream patches this patch also refactors the allocation, deallocation and registration handlers to consider the requested type and perform the necessary actions according to it. Since not all future device memory types will be such that are mapped to user memory, the mandatory page index output attribute is modified to be optional.

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.
