I'm not sure I understand how this is supposed to work. Do you mean that a word in the AT_SYSINFO page would give you a feature-bitmap? If so, how does that work with old kernels (where you don't get AT_SYSINFO) at all, but you still need to know the kernel revision? BTW: On ia64, the gate page that AT_SYSINFO points to is "execute-only", so we can't read stuff directly off of it. Of course we could have a read-only page, but I don't see the point of wasting a page given that we can now do (simple) syscalls in ~35 cycles. --david
