No, the whole system memory mappend (beside of boot memory) beyond
1^32. Like (from /proc/iomem):

6000100000-60003fffff : System RAM
6003000000-6033dfffff : System RAM
6033e00000-6043ffffff : System RAM
6044000000-6045b9efff : System RAM
6045b9f000-60f7ffdfff : System RAM
16000100000-160003fffff : System RAM
16003000000-16033dfffff : System RAM
...
