This driver isn't enabled most places because of the ISA config
dependency, but alpha still has it. And I think the 'Jensen' actually
did have an ISA slot.
However, it doesn't build cleanly, because the "Vortex bus master" code
just casts the skb->data pointer to 'int':
outl((int) (skb->data), ioaddr + Wn7_MasterAddr);
which is all kinds of broken. Even on a good old traditional PC/AT it
would be broken because the high bits will be random kernel address
bits, but presumably the hardware ignores those bits. I mean, it's ISA.
We're talking 16MB dma limits. The "good old days".
Make the build happy with this kind of craziness by using the proper
isa_virt_to_bus() handling that the full bus master code uses anyway
(the Vortex bus mastering is a limited special case).
Who knows, this might even work.

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.
