[SPARC64]: Do not allow mapping pages within 4GB of 64-bit VA hole.
The UltraSPARC T1 manual recommends this because the chip could instruction prefetch into the VA hole, and this would also make decoding certain kinds of memory access traps more difficult (because the chip sign extends certain pieces of trap state).
