It is not possible to get DMA32 zone memory through kmalloc, causing the vboxguest driver to malfunction due to getting memory above 4G which the PCI device cannot handle. This commit changes the kmalloc calls where the 4G limit matters to using __get_free_pages() fixing vboxguest not working on x86_64 guests with more then 4G RAM.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
