[PATCH 4/5] s390/kdump: Mark __machine_kexec as __noreturn

[Thorsten Blum]

__machine_kexec() either ends by calling the non-returning function
__machine_kdump() or the non-returning function __do_machine_kexec(),
and therefore also never returns. Annotate it with the __noreturn
attribute to improve compiler optimizations.
