This adds support to create userptr BOs on restore and introduces a new ioctl op to restart memory notifiers for the restored userptr BOs. When doing CRIU restore MMU notifications can happen anytime after we call amdgpu_mn_register. Prevent MMU notifications until we reach stage-4 of the restore process i.e. criu_resume ioctl op is received, and the process is ready to be resumed. This ioctl is different from other KFD CRIU ioctls since its called by CRIU master restore process for all the target processes being resumed by CRIU.

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.
