OK.

Not so sure about this one. Does randomize_va_space actually make sense in a nommu environment? I guess we could load relocatable binaries into a randomised place, but I'm not sure that this is implemented?
If no, then it would make more sense to do
#define randomize_va_space 0
for nommu, so the relevant code gets thrown away by the compiler. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
