Modified Files: src/share/man/man7: stack.7 Log Message: stack(7): Fix diagram of non-main thread stacks. Had stackaddr (pthread_attr_setstack parameter, lowest-numbered virtual address of stack region) confused with stack base (where the stack grows from, which is the highest-numbered virtual address on machines where stack grows down).
