I explained it 3 days ago, so once again:
x86-64 binaries and shared libraries are required to handle page sizes up
to 1MB and as RE and RW segments can't be on the same page, this means they
must not share the same 1MB page.
Just google for ELF_MAXPAGESIZE or look at the libraries using readelf -Wl.
