Factor the main copy page to ram routine out into a helper that acts on a single page and which doesn't require the nouveau_dmem_fault structure for argument passing. Also remove the loop over multiple pages as we only handle one at the moment, although the structure of the main worker function makes it relatively easy to add multi page support back if needed in the future. But at least for now this avoid the needed to dynamically allocate memory for the dma addresses in what is essentially the page fault path.

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.
