This implements the KFD CRIU Restore ioctl that lays the basic foundation for the CRIU restore operation. It provides support to create the buffer objects corresponding to the checkpointed image. This ioctl creates various types of buffer objects such as VRAM, MMIO, Doorbell, GTT based on the date sent from the userspace plugin. The data mostly contains the previously checkpointed KFD images from some KFD processs. While restoring a criu process, attach old IDR values to newly created BOs. This also adds the minimal gpu mapping support for a single gpu checkpoint restore use case.

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.
