[PATCH 0/5] split ET_DYN ASLR from mmap ASLR

2015-02-26 Thread Kees Cook
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,
