commit e3f44742bbb10537fe53d83d20dea2a7c167674d upstream. While debuggigng why X would not start on mips64 Sgi/O2 I found the phys adress being off. Turns out the gbefb passed the internal dma_addr as phys. May be broken pre git history. Fix by converting dma_to_phys.

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.
