I hadn't really given it much thought. Is there a simple way to determine if the cpu is power 7 or newer? It's not elegant, but a program could call mmap() with PROT_SAO set and check for errno == EINVAL. Then call again without PROT_SAO, if it needs to. > We haven't defined a user-visible feature bit (and besides, we're really > getting short on these...).
