commit 46480ef35e471888e533d31e72523f6e0592baf8
Author: Daniel Axtens <dja@axtens.net>

    powerpc/sparse: Make ppc_md.{halt, restart} __noreturn
    
    PowerNV marks it's halt and restart calls as __noreturn. However,
    ppc_md does not have this annotation. Add the annotation to ppc_md,
    and then to every halt/restart function that is missing it.
    
    Additionally, I have verified that all of these functions do not
    return. Occasionally I have added a spin loop to be sure.
