From: Mike McGowen <mike.mcgowen@xxxxxxxxxxxxx>
Map full length of PCI BAR 0 at driver init.
During driver initialization, the driver must make a kernel call
to map the controller registers into kernel address space.
A parameter to this call is the length of the memory to be mapped.
The driver is specifying the wrong length.
