Handle this by having the driver allocate at least enough MTT entries to
cover 2 * totalram pages.
just curious, why we want to cover totalram? also the commit title
has mxl4 instead of mlx4

The current driver defaults to 1M MTT segments, where each segment holds
8 MTT entries. This limits the total memory registered to 8M * PAGE_SIZE
