extern void show_stack(unsigned long *stack);
This is not good. In general, it is not possible to do a reliable
backtrace with just a stack pointer as a starting point (it is
necessary to have access to the entire "preserved" machine state
instead). I'd suggest to either change the argument to a task_struct
pointer (and update half a dozen platforms or so accordingly), or to
leave the declarations platform-specific like they were before.
PS: force_sig_info() still drops the siginfo pointer passed to it.
Will you fix this soon as promised?
