Hmm, I am not completely aware about the proposed mmap interface
for 128TB and beyond till 512TB by Kirill on x86. If both powerpc
and x86 will have the same semantics, then this test is generic
enough to cover both the architectures and will move it into
selftests/vm/ instead of current selftests/powerpc/mm.
