For some odd reason dell_rbu actually seems to want the physical and not a bus address for the allocated buffer. Lets assume that actually is correct given that it is BIOS-related and that is a good source of insanity. In that case we should not use dma_alloc_coherent with a NULL device to allocate memory, but use GFP_DMA32 to stay under the 32-bit BIOS limit.

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.
