commit 637543a8d61c6afe4e9be64bfb43c78701a83375 upstream.
Current logic incorrectly uses the enum ioapic_irq_destination_types

If the unwinder is called before the ORC data has been initialized,
orc_find() returns NULL, and it tries to fall back to using frame

The LEAQ instruction in rewind_stack_do_exit() moves the stack pointer
directly below the pt_regs at the top of the task stack before calling
do_exit(). Tell the unwinder to expect pt_regs.
