You don't seem to have followed the thread.  For UML, the address
isn't a hint - it's a requirement.  Tossing random numbers into your
code until a particular test works isn't really the way to go.  In
this case, we are looking at mmap_min_addr being set at 0x10000, but
which may be set to 0x20000 someplace else.
