I was hoping for a generic function that checks wether a given memory
range is valid.
In my case, it should have checked sizeof(struct task_struct) at addr
before calling kdba_bt_address().
I will add such a check to kdba_bt_stack_ppc now. How do other archs
deal with 'bt 72' (which should have been 'btp 72')?
