Yes... what I was asking was "do things actually break if you leave that out, or does the binfmt_elf loader honour the 'x' permission on the PT_LOAD entry for the data/bss region, meaning that it all just works anyway?" I did an objdump -p on some random 32-bit binaries, and they all have "rwx" flags on the data/bss segment (the second PT_LOAD entry). And when I look in /proc/<pid>/maps, it seems that the heap is in fact marked executable (this is without your patch). So why do we need the hack in binfmt_elf.c?
