This separates ET_DYN ASLR from mmap ASLR, as already done on s390. The various architectures that are already randomizing mmap (arm, arm64, mips, powerpc, s390, and x86), have their various forms of arch_mmap_rnd() made available via the new CONFIG_ARCH_HAS_ELF_RANDOMIZE. For these architectures, arch_randomize_brk() is collapsed as well. This is an alternative to the solutions in: https://lkml.org/lkml/2015/2/23/442 Thanks! -Kees
