[PATCH 4/4] s390: Reduce ELF_ET_DYN_BASE

2017-06-22 Thread Kees Cook
Now that explicitly executed loaders are loaded in the mmap region, position PIE binaries lower in the address space to avoid possible collisions with mmap or stack regions. For 64-bit, align to 4GB to allow runtimes to use the entire 32-bit address space for 32-bit pointers. Signed-off-by: Kees
