Scratch page is in VRAM, and therefore requires 64K GTT layout. In GGTT world this just means having 16 consecutive entries, with 64K GTT alignment for the GTT address of the first entry (also matching physical alignment). However to keep things simple just dump it into system memory, like we already do for ppGTT. While we are here, also give it known default value.

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.
