If an mlx4 device with default FW (which gives a UAR BAR size of 8 MB) is used in a system with 64 KB pages, then there are only 8192/64==128 UAR pages available. However, the first 128 UAR pages are reserved for use with event queue doorbells, so no UAR pages are available to do anything else with, which means that the driver cannot work. The current driver fails with a fairly cryptic "Failed to allocate driver access region, aborting" message in this situation. Fix the driver to detect the problem earlier and print out a clearer description of the problem and a suggestion of how to fix it (use a new firmware image).
