-         PAGE_SIZE order which is greater than or equal to the requested buffer
-         size. This works well for buffers up to a few hundreds kilobytes, but
-         for larger buffers it just a waste of address space. Drivers which has

-         With this parameter you can specify the maximum PAGE_SIZE order for
