Ilya Leoshkevich a1d863ac3e s390/unwind: fix mixing regs and sp ... unwind_for_each_frame stops after the first frame if regs->gprs[15] <= sp. The reason is that in case regs are specified, the first frame should be regs->psw.addr and the second frame should be sp->gprs[8]. However, currently the second frame is regs->gprs[15], which confuses outside_of_stack(). Fix by introducing a flag to distinguish this special case from unwinding the interrupt handler, for which the current behavior is appropriate.
