When unwind_frame() reaches the bottom of the irq_stack, the last fp points to the original task stack. unwind_frame() uses IRQ_STACK_TO_TASK_STACK() to find the sp value. If either values is wrong, we may end up walking a corrupt stack. Check these values are sane by testing if they are both on the stack pointed to by current->stack.
